SSD DRIVE INFO
SSD Drives have matured considerably since Intel released there 2 1/2” drive in early 2008, many other makes were released, none that were really as good as the 1st generation Intel drives, these early drives with Jmicro controllers and Samsung controllers suffered stuttering and Micro freezing problems and there overall performance was average compared to the Intel offering, which didn't suffer from the same problems. They were also extremely expensive for what they offered.
For those people needing more information about buying a ssd drive LesT a Extreme Overclocking member has his own website, The SSD Review with a lot of information on these drives.
Technology as we all know, doesn't stand still and the release of the Indilinx Barefoot Controller leveled up the playing field considerably.
Since then, many different makes, by many different manufacturer's ( 300 and counting ) of SSD drives have been marketed with different makes of controllers, all with differing performance levels.
Firmware for these drives and controllers as also improved, making stuttering and freezing a thing of the past.
Trim on SSD Drives
When I first wrote this article/thread, which was for my own benefit and was eventually turned into this thread, as it is today, trim was not available on ssd drives, when it did arrive, there were mixed idea’s on how it worked, a lot that was incorrect at the time, a lot of new users do not understand the use of Trim even today, explanations tend to be very technical as trim is a complicated issue at the best of times. I found a simple explanation for the implementation of trim in late 2009, I came across it again the other day, it still holds true today so here’s the link, ( I know you are going to point me to AnandTech explanations, there are links in this thread, if your a technically minded person, then AnandTech’s articles may be a better option ) this simpler explanation is still active in late 2011. As you can see if you carry on reading and don’t turn off, how complicated it can be for a non-technical user of ssd drives. So here’s my explanation of trim. Remember this a generalization of most ssd drives, it’s a lot easier when your dealing with your own ssd drive.
Trim and it’s association with GC ( garbage collection )
Trim varies depending on how the controller’s "GC" handles the use of Trim ( Win7 ). Trim is activated, by deleting files in the OS ( Win7 ), it doesn’t actually trim the ssd drive, but marks the block/file header’s with a 1 making that block/file available for being re-written or deleted. Trimming is actually done by the GC and will only work if the block doesn’t contain other files that haven’t been marked deleted, but this again depends on how GC is implemented, the GC can wait till the block is full, then move un-deleted files to another block allowing for the block to be trimmed ( GC ), in doing this, the GC uses a lot more write amplification than it does if Trim in win7 has previously marked these blocks/files for deletion, flash memory can only be ‘deleted’ if all the information in that block as been marked with 1, this allows the whole block to be re-written. GC can only erase/Trim a full block, not individual files or pages.
What trim does
What trim does is mark these blocks/files etc and make it simpler for the inbuilt GC ( garbage collection ) to recognize the blocks that are available for further use, on some controller’s this will not necessarily happen immediately, it depends on whether the controller as been designed for “idle” use, “on the fly” use or “stand by use”, GC/Trim can be brought into use in many different ways, having the computer sitting with the bios open, having the computer idling at log in, placing the computer in stand by mode, deleting files or just simple idling the computer for a hour or so or overnight
Re-formatting a modern ssd drive also triggers trim on most modern ssd drives. It’s a matter of finding out how the controller in your particular ssd handles the garbage collection. You will find the most efficient way is by experimentation or by other members passing on there particular way of doing it.
Low level formatting
Low level formatting used on conventional HDD drives writes mainly 0’s to every cell on a SSD drive, it’s the opposite to how flash memory actually works, if you low level format with Win7 or any software that writes 0’s or 0’s and 1’s to the individual cells, you are not necessarily cleaning the ssd drive completely, ( hence the need for secure erase software on older ssd drives ), you can actually make the performance worse. As technology changes ( 2012/13 ) and the way GC/Trim have improved there will be less need to secure erase ssd drives, simply formatting or re-formatting the ssd drive will in most cases trigger the internal GC or Trim in win7.
If you use software designed for writing 1’s to each cell, like you would if it was designed for ssd drives, this will “clean” the drive and is a good thing to do if you are selling the drive, or as a last resort or if you are having problems with your ssd drive. The downside of using this type of erasure, is that it not only takes a long time it uses high write amplification and if used regularly can reduce the flash cells life expectancy considerably, these type’s of deletions bypass most controllers durawrite capabilities ( the way controllers extend the life expectancy of the ssd’s individual MLC cells ), Durawrite ( Sandforce ), other controllers have this technology in some form or other, it increases MLC life expectancy by between 5 and up to 30 times depending on the design of the controller. Durawrite is LSI Sandforce’s name for this type of technology, other controllers use similar technology for extending cell life.
Basically a command line program like dispart and dispar will secure erase a ssd drive either by writing to the individual ( “Cleanall“ command ) cells or simply marking the blocks to be deleted with a 1 ( “Clean” command ), you need to use the latter which takes only seconds and will return the majority of ssd's to a new state without impacting too much on write amplification. XP may not have the “Clean” command it was added when Vista was released. New commands are added each time a new OS is released.
That’s how I see the use of GC and Trim in win7 today ( Nov 2011 ). Note! Most ssd software, tool boxes etc use the inbuilt win7 diskpart commands, to make it easier than using the command line. There is a explanation for the use of diskpart and can be found HERE, but NOTE! It’s written with conventional hard drives in mind, not ssd drives.
In the case of most Toolboxes provided by manufacturer’s, the OCZ Toolbox is a typical example, they are incompatible with Intel’s RST driver, you would need to use Diskpart from the command line. Also Toolboxes will in most cases, not secure erase a ssd with a OS on it or if the ssd drive is in use as the OS drive eg. ( “C:/” partition ).
If you want to secure erase an OS drive you need to delete all the partitions on the drive including any hidden partitions, there’s an excellent tutorial on the Intel toolbox on LesT’s website, TheSSDReview here’s the Link.
You will have to use Diskpart or Diskpar from the Dos prompt, you can’t be in windows with the ssd drive you intend to erase. This is mainly if the toolboxes fail to work and deleting the partitions refuses to solve the problem.
I’m sure there are exceptions to what I have written and easier ways of explaining trim or secure erasing some types of ssd drives. All I ask is you don’t isolate passages out of context, please read the whole article, before you tell me I’m incorrect. There are a lot of more informative people out there than me on this subject, so I’m open to criticism on the subject. I want to impart only the correct facts on this thread.
Trim and the IDE issue
The Intel IDE drivers after Vista sp2 are fully compatible with the trim command , but for trim to pass through this command, the ssd controller itself has also got to be compatible with IDE mode, eg. Intel drives with the Intel controllers are ( according to Intel ) fully compatible. The Crucial M4 appears not to be, other controllers optimized for AHCI may also not be compatible. I can’t comment on the Intel 510 as I’ve only ever used them in AHCI mode.
Here’s an explanation that’s not too complicated, its from StorageSearch.com, here’s the LINK.
Also from StorageSearch.com, a simple explanation for the need for overprovisioning, same link as above. This actual link covers a number of technologies used by the ssd controller in ssd drives. Overprovisioning improves write performance, if the ssd is used in a high write situation, increasing the overprovisioning will improve performance and write endurance, in a high read situation too much can hinder performance, in a os situation the 7% supplied on most client drives, in most cases is probably adequate depending on it’s use, if there’s a lot of writing done to the drive daily, reducing the partition size, which will increase overprovisioning by a small amount may improve performance.
Also not overfilling a ssd will help it’s performance, some drives will maintain performance in a full state better than others, it’s probably better not to go above 70% in most cases.
There’s a excellent article recently released ( January 2013 ) by LSI employee Kent Smith which explains the use of overprovisioning and its improvement to the Trim command. Here's the Link.
TLC memory and SSD Drives
Up until now (Sept 2012 ) TLC ( triple cell ) memory, ( mainly used on usb flash drives ), as not been an option for ssd drives, Samsung’s new 840 drive as changed all that, it uses Samsung's TLC Toggle memory, TLC memory as been experimented by ssd drive manufacturers for quite a few years, up until now it hasn’t been a viable option due to reliability, cell life, bit leakage, lower performance and various other reasons. This was once the case with MLC memory which is now used on all client drives and considerably lowered the price of ssd drives. Micron also now as viable TLC nand memory due for release, probably in 2013.
The major advantage of TLC memory, it will be cheaper by an estimated 30% once it matures and less chips are required for the same capacity as MLC memory. ( I should also note, Samsung website no longer quote’s endurance figures, They’ve been removed. ). Here’s a link from AnandTech that explains the technology.
Migrating the OS to a SSD drive.
There are a lot of people "for and against" when it comes to the subject of Migration or a clean install, I’ve always migrated all of my OS drives and before ssd drives, conventional hard drives, I’ve had absolutely no problem doing it and performance as never suffered. Since Vista was released, I’ve only reformatted twice, once for the Vista Ultimate 64b OS and once for the Win7 Ultimate 64b OS.
I can understand that from a benchmarking point of view or a new build with new hardware, a clean format is the only way to go, but I can’t see the point of not migrating otherwise, if the OS drive is properly maintained, especially on a laptop where clean formats are annoying, ( a hard drive or OS with errors generally will not clone, the clone usually fails, most cloning software will use Windows ChkDsk to test the drive prior to cloning if this fails so will the clone ), all I’m saying is I personally have not had bad issues cloning drives with software that’s compatible with the OS being used.
My own laptop OS drive usually has between 200 and 300gb/s of data on it, I’ve had no trouble migrating and cloning backups for any of the drives, I am presently using a 512gb M4 ssd drive. I’ve also used an Intel 160gb G2 and two Intel 510 256gb ssd drives in that period of time on both a Desktop computer and the Laptop ( 3 year old ). The only problem I’ve ever had was a faulty eSata cable.
Probably the biggest problem when migrating is moving an early IDE setup, this can be done with certain changes, the IDE set-up needs to be changed to AHCI in the motherboards BIOS, most modern ssd drives are optimized for AHCI mode, some will not even work in IDE mode, in this case it’s advisable to change to AHCI mode prior to the change to the ssd drive.
This can be done by disabling the IDE driver in the windows registry, rebooting and going into the bios and changing the bios setting to AHCI, saving the setting and windows should boot normally. The boot drive can then be migrated ( cloned or imaged ) to the ssd drive.
Good migration software such as Acronis will re-align an XP partition and win 7 will detect the ssd drive and make some changes accordingly (I mention Acronis, not because it's the best, it's what I am familiar with ).
Trim in win7 should be activated by default, this can be easily checked using the win7 command line or checking with a application such as the free version of ssd Life, also certain benchmarking software will tell you whether trim is active. There is also a free program called Trimcheck that can determine that your ssd drive as actually been trimmed.
Advantages: -- You simply swap drives after the migration, time 2 hrs including swapping drives. The major advantages is that your computer or laptop will work with either drive and the old drive can be kept as a OS back-up.
Disadvantages :-- I’ve yet to find any on a straight forward disk drive or ssd drive update.
Problems :-- Cloning can fail for any number of reasons, most are not related to the cloning procedure eg. bad cables, incompatible software or hardware, disk drive file errors, disk drive hardware errors, malware, with raid arrays you need cloning software that is capable of cloning raid arrays with your type of hardware.
You’ve also got to realize an ssd drive when cloned may be as much as 75% - 80% full, it’s not going to have the same benchmarks as a drive with only a OS on it. The GC ( garbage collection ) on most modern drives will return the drive to it’s natural speed in a short period of time anyway.
One of the major problems most people face when moving to a ssd drive from a conventional drive, the conventional drive will be considerably larger and may only consist of a single partition, when migrating, the data contained on the larger conventional drive as to be less than the usable capacity of the ssd drive, excess data needs to be copied to another drive before cloning / imaging can take place. There is a difference between cloning and imaging, with most free cloning software you can't clone partitions only full drives but you can image partitions or parts of a drive.
The downside of imaging (in most cases), any errors on the disk drive or OS will be carried over to the new drive and the original image may get deleted from the old ssd or conventional drive, the drive is usually not tested with ChkDsk by the imaging software, my advice before either cloning or imaging is to do a comprehensive virus and malware check and in the case of imaging to run windows ChkDisk manually prior to doing the imaging.
Cloning and imaging software is changing and being updated all the time, some cloning software now as the capability of doing partitions or just part of a disk drive, to get this capability you may have to upgrade your software.

Older Hawk drives had re-branded SF2281, it appears Toshiba may have re-worked the marvell silicon to include internal caching.
Toshiba T6UG1XBG Controller ( Sata II - 3Gb/s ). A decent performing controller. Big improvement on previous Toshiba controllers prior to 2010. Review at BenchMarkReview Jan.2010.
We will see further improvements, better technology and better controllers released in 2012/13, below is a Alphabetical list of SSD drives available as of July 2012/13, I hope the Information and the Links supplied will help people choose the ideal SSD Drive for there needs.
I also intend to upgrade this list as new drives and information is released. Anywhere you see a lack of information, it's either because I've been unable to find the info or unable to verify it. The info on drives ( as there are now over 400 builders and manufacturers of ssd products ), the list will be limited to the more popular & notable drives.
The majority of these drives use MLC Nand Flash Memory and are for use in non- enterprise situations, such as desktop and laptop use, this type of memory is not as hardy as SLC type memory and as only about a tenth or greater the lifespan, MLC memory is estimated to be capable of above 3000 to 5000 write operations per cell, memory quality and the controller, both have a bearing on this figure, SLC memory used in enterprise drives, for server applications, as a estimated capability of 30,000 to 100,000 write operations, due to this, the SLC enterprise drives cost considerably more. It should be noted that controller development as vastly improved the lifespan of MLC memory making the lifespan of ssd with it much longer, lifespan appears to be no longer an issue, reliability and compatibility are now the main concern.
The read and write speeds are those issued by the manufacturer using ATTO software. Sequential speeds are less important than random access speeds. These performance figures can vary depending on the size of the SSD drive, the figures posted here are mainly for drives around 125/256GB, smaller drives of the same series may have lower performance write figures, larger drives, better performance write figures.
These Sequential speeds are far less important than Random speeds when the SSD is used as an OS drive, sequential write speeds become important when the drive is needed for rendering, re-authorizing movies etc. ( my opinion only ). The higher the IOP's rating, the better a drive is at multitasking. Most drives released in 2012 have extremely high IOP's. I should also add that huge iops figures on client drives are very rarely maintained in high write situations, a drive may start at a figure of 70,000 iops but with sustained writing can drop to as low as 10,000 after ½ hour of sustained use, enterprise drives may have lower advertised iops but the figure will drop only fractionally after days off sustained writing.

New firmware 0009 as been released improving the M4 reliability and performance. The latest firmware is ver. 000F ( as of Sept 2012 ).
The variation in performance between the different capacities of the M4 ssd drive is quite large, this link from Tom’s Hardware tests the four different capacities, the firmware in the test drives is 0006.
Crucial M500 ( Sata rev.3 - 6Gb/s ) –
Marvell 88SS9187-BLD2 Controller. Sequential read 500MB/s, Sequential write speeds vary on the two lower capacity’s, 120gb/130MB/s, 240gb/250 the 480gb and 960gb are 400. There is usual support with GC and Trim in Win7/8, The cache or buffer is Micron 256MB DDR3 SDRAM cache MT41K256M16HA-125 on the 960gb drive, there are 4 capacities 120, 240, 480 and 960gb, The memory modules on the 960gb drive are Micron 20nm MLC MT29F512G08CKCABH7 onfi Ver 3.0 ( higher maximum interface speed and lower voltages ) with each being a capacity of 64GB. The M5 as improved power protection, adaptive thermal technology, the drive throttles back if it becomes overheated, and encryption technology. The performance and technology are first rate, ( according to TheSSDReview ) alongside the Samsung Pro and Vector ssd drives at this point, offering no ssd toolbox and only a 3 year warranty is a bit disappointing, but Crucial fans will be used to that. Website and reviews at TheSSDReview, Storage review.com and Anandtech. The more thorough testing done at Storage Review.com showed the drives weaknesses and putting it much lower on the performance list, the Samsung Pro and the Vector are still better propositions for overall performance, the drive as decent performance but needs to be offered much cheaper than the Pro or Vector to be a viable option.
Putting performance issues to one side, the drive is compatible with win 8 edrive standards and hardware accelerated bitlocker encryption which as been improved over the win7 version, an explanation at Anandtech shows the differences between the Samsung pro and the M500 where encryption is concerned.
Also better power protection similar to that supplied by Intel drives and the availability of a cost effective 960gb drive size make the M5 series a more overall viable option. The downside is the move to the 20nm onfi v3.0 memory which even though it makes a 960gb drive possible without having to use triple bit memory, the larger pagefile and block size effects trim speed and overall performance. Overprovisioning has increased from the standard 7% of the M4 to 14% probably due to the higher error rate of the memory.
The Anandtech review places a lot of emphasis on the nand type and it’s weaknesses, this is not a top tier ssd drive, it’s a excellent value mid tier drive designed for masses rather than a performance drive. It’s main rival appears to be the Samsung 840 rather than the Pro. The benchmarking was mid range, real world testing on the other hand was outstanding. This is an early opinion which could change due to the outstanding real world figures.
For the average user the M500 appears to be a excellent ssd drive.
Crucial M550 ( Sata rev.3 - 6Gb/s ) –
Marvell 88SS9189 Controller. Sequential read is 550MB/s, Sequential write speeds vary on the smallest capacity, 128gb/350MB/s, 256gb, 512gb and 1024gb are 500. There is usual support with GC and Trim in Win7/8, The cache or buffer is Micron 256MB DDR3 SDRAM cache MT41K256M16HA-125 on the 1024gb drive, there are 4 capacities 128, 256, 512 and 1024gb, The memory modules on the 1024gb drive are Micron 20nm MLC MT29F512G08CKCABH7 onfi Ver 3.0? ( higher maximum interface speed and lower voltages ) with each being a capacity of 64GB, reducing the size of the nand modules compared with the M500 128gb as improved write performance on the smaller drives. Crucial as also reduced overprovisioning, increasing the size of nand memory available to the user. This drive has all the improvements of the M500 and with the new controller better read and write speeds on the smaller and slightly better on the larger drives, the performance is still not as high as the Sandisk Extreme 2 which uses the same controller and Evo 840 both include some sort of pseudo SLC cache.
The tests appear slightly disappointing on the synthetic benchmarks but top tier in real world testing, being a Crucial the drive will be reliable across most platforms it’s performance is close but still below the top tier drives in some tests, but still an excellent ssd drive for general use, uses slightly more power than M500. Website and reviews from Anandtech and Tweaktown.

INTEL ( 3 yr warranty period )
New firmware as been released for the Intel silver G2 drives, the new firmware is available from Intel at this link, the new firmware is 2CV102M3 and deals with a number of issues including slow boot up times on Sata III motherboards. NOTE! Certain notebooks need to be changed to IDE ( Lenovo ) for the update to work and any drive passwords need to be disabled. There are two ways of updating the firmware on Intel ssd drives, you can do it through the Intel Toolbox or use the more reliable Intel Solid State Firmware upgrade Tool. This firmware tool covers all the Intel drives old and new. Both These Software Applications can be found on Intels ssd download page. Updated Dec 2011.
NEW! Intel 311 ssd drive ( Larson Creek ) ( sata II – 3Gb/s –
Intel PC29AS21BA0 processor. This is a cache drive with a 20gb capacity, optimized for Intel Smart Response Technology, which debuts with the Intel Z68-Express chipset and works with the entire Sandy Bridge series. Read 200, combined IOP’s 40,000. The memory used is Intels 34nm SLC flash.
EOL! Intel 320 series ( G2 refresh ) G3 ssd drive ( sata II – 3Gb/s ) –
Intel PC29AS21BA0 Controller. Read 270, write speeds varies depending on the size of the drive, 40gb / 45MB/s / 3.7k IOPS, 80gb/90/10k, 120gb/130/14k, 160gb/165/21k, 300gb/205/23k, 600gb/220/23k, these are Intels specs. These drives use a Hynix 64mb sdram buffer and the controller as 256k on-die buffer, The drive uses these buffers for caching memory maps etc. Power failure caching is done by a series or array of multiple capacitors ( info Anandtech review ). This system is considered by Intel as being more reliable than a single large capacitor. Spare non-usable ram is 12.8% ( over-provisioning ). The capacity windows will see is approximately 13% less than the rated capacity. Also included in the g2/g3 controller is AES-128bit data compression, not activated on the G2. Dec 2011 This drive still as the exception 13x ( 8mb ) problem which new firmware as failed to resolve, not a drive to buy until the problems sorted, this problem can happen with a sudden loss of power and by simply coming out of sleep mode, a ups does not solve the problem, rmaing the drive doesn’t seem to help either. Note* not all users have this problem, but worth checking out before buying. Here is a thread about the problem on the Intel forum.
Website and Comprehensive Reviews from AnandTech and LegitReviews.
Intel 335 series ( Sata3 – 6Gb/s ) –
Sandforce SF2281 Controller, Read 500 write 450, usual support for GC and Trim in Win7, the drive is available in capacities of 60gb, 120gb and 180gb of Intel 29F16B08CCME2 25nm Synchronous nand memory, this memory is similar to that of the 520, Intel bins all it’s silicone, the 520 uses memory modules from bin1 the 330 from bin 2 which is of a slightly lower quality, the effect being slightly lower performance and lower life cycles than the top tier bin 1 memory. Website and Reviews at TheSSDReview and TomsHardware.
EOL! Intel 510 series SSD Drive ( Sata III – 6Gb/s ) -
Marvell 88SS9174-BKK2 Controller, this is the similar controller to the RealSSD M4, the M4 controller as a slight revision, the Hynix H5TQ1G638FA 125mb ddr3 buffer is the same, as in the M4 except the M4 uses two to double the size of the buffer, Intel have used there own firmware on the drive, 250gb/125gb Sata III speeds, sustained sequential read 500/450MB/s, sustained sequential write 315/210MB/s. Sata II speeds, sustained sequential read 265/265 MB/s, sustained sequential write 240/200MB/s. Note! These according to Intel are sustained sequential speeds and are usually lower than standard or partial sustained sequential speeds. Random 4kb speeds at a 32 queue depth are (250gb/125gb) Read 20,000 IOPs and write 8,000 IOPs. The Nand Flash memory for these drives is Intel 29F6B08JAMDD MLC 34nm Nand Flash memory, 34nm memory is more reliable, as better performance figures, as a lower error count and lasts longer than the newer 2xnm flash memory. 2xnm is cheaper to manufacture. Intels Data Migration, Toolbox and SSD Optimizer software are available for these drives.
Benchmarks taken for the 510 by Tom’s Hardware and Legit Reviews 2x256gb Intel 510 in Raid 0, show clearly that the drive is optimized for movement of large files rather than it’s use as a OS drive, the IOPs and random readings are poor compared to the latest SF2200/2500 Controllers, but excels better at large file movement. The 4KB transfers are poor, the 512KB transfers are excellent. A very disappointing drive, as the early benchmarks do not seem to reflect Intel's written specifications. The firmware on these drives is PWG2.
EOL! Intel 520 series ( sata3 – 6 Gb/s ) –
Sandforce SF2281 Controller, Read 550 write 520, usual support for GC and Trim in win7. Capacities available are from 60 to 480gb of Intel 29F16B08CCME2 25nm NAND flash memory, this memory is similar to the newer 330 but is top binned 5K compared to the 330’s which is rated at 3K this drive series as been released to benchmarking sites, here are reviews from from TheSSDReview and Tom’sHardware. Performance is considered in some cases better than the OCZ Vertex 3 and the OCZ Vertex Max Iops, but looking at more benchmarks shows the 520’s performance similar but not better than the Vertex 3 Max IOPs or the Kingston HyperX. The SSD Review as also tested three of the 256gb Intel 520’s in Raid 0 on a Highpoint 2720SGL raid controller, HERE is the link.
NEW! Intel 530 series ( sata3 – 6 Gb/s ) –
Sandforce SF2281 Controller, Read 540 write 490, usual support for GC and Trim in win7. Capacities available are from 80 to 480gb.
NEW! Intel 730 series ( sata III – 6Gb/s ) –
Intel PC29AS21CA0 Controller. Read 550 write 470, there are two buffer chips. The 730 series comes in two capacities of 240gb and 480gb of Intels 20nm MLC nand flash memory, endurance is 70gb per day and the warranty period is 5 years. Firmware on release is L2010400. Even though this drive will run in laptops it performs far better in Desktops, not really considered for use in laptops due to its power needs. Website and reviews from Tweaktown
NEW! Intel DC S3700 enterprise series ( Sata 3 – 6Gb/s ) –
Intel S3700 controller (PC29AS21CA0 ). Read 500 write 460, the buffer size varies with the 800gb drive having 1gb of dram, as explained previously this is Intels 710 replacement enterprise drive, the overprovisioning as been reduced, the 200gb drive as a extra 64gb of nand memory compared to 120gb on the 710 drive, overprovisioning is used by the controller for wear levelling, block re-cycling, redundancy and block replacement. The drive comes in capacities of 100gb, 200gb, 400gb and 800gb, the memory is the same as the 710 using Intels 25nm HET MLC nand. The pricing is also lower than the 710 drive. Review at Anandtech.

OCZ SSD Drives. ( 3yr warranty period )
Dec 2013 OCZ as been acquired by Toshiba so I believe drives will be sold under OCZ name.
End Of Line drives ( EOL ) marked in green that have not been removed are no longer sold or supported, the warranty on these drives as usually elapsed.
BSOD with the new Sandforce drives
I noticed in a OCZ forum listing, that changing to Intels latest Enterprise version of the RST drivers as in some cases appeared to solve this problem, here’s the LINK. After further study, it’s hit and miss, but you might find the link interesting.
Note# When flashing firmware on any OCZ ssd drive, consult the OCZ forum stickies for the exact procedure especially if the drive as not been flashed for quite sometime and is not up to date.
Indilinx Barefoot Controlled SSD Drives.
Having continuous problems with your Indilinx drive Check this forum link for a possible solution.
Firmware “ Arowana” FW 3.55 released 28 mar 2012 for barefoot drives manufactured after Dec2009, the update increases over-provisioning which in turn gives the better sequential and random write performance, also increasing the longevity of the drive at the cost of reduced capacity ( 6-7%) and reduced read performance. This update is destructive so the drive needs backing up. The OCZ identity tool needs to be used to check the drives code against the codes that are compatible for the update
Firmware FW1.70 as been released for the barefoot drives. Requires FW1.60 before flashing.
Firmware FW1.60 released for Indilinx drives, check Vertex section for Links.
Indilinx Everest Controlled Drives.
New Firmware Ver. 1.13 as been released for these drives the download can be found on the OCZ ssd Support page, here are some cautions related to the update.
• Updating the firmware from the toolbox is not supported when Windows is running off the drive you are trying to update.
• WARNING: This is a Destructive Flash, back up all data on SSD. Proceeding with this update will result in complete loss of data on the SSD.
• -The toolbox requires MSAHCI drivers to run.
-The Intel X79 chipset is not yet supported.
-Drives must not appear as "Drive0" for updates. Please ensure update is not performed on a disk set to primary.

Note! If your having continuous problems with your Indilinx ssd drive and having to continually to re-install Windows, the solution for this is to have your drive flashed with a specific destructive firmware. You need to download the OCZ Identity tool and email RyderOCZ with the relevent information, information on doing this can be found HERE. There is an email link on the bottom of his posts. It appears these indilinx drives can start corrupting windows installs on a regular basis and the only solution is to run a specific destructive firmware supplied by OCZ.
Note! OCZ advises using the latest Intel drivers, rather than using the Microsoft native drivers on most of there drives, including the Sandforce controlled drives, the Microsoft native drivers can cause ssd drives to run slow and cause errors with the trim function.

Website and reviews at Anandtech and TheSSDReview.
Price would need to be similar or even lower than Samsungs EVO drives to be competitive, my choice would be the EVO or the Crucial M550. We are seeing little or no performance improvements in the sata3 drives, Anandtech believes this is due to manufacturers concentrating on the PCIe drives and I am in total agreement.

The memory for this ssd drive is Samsungs 19nm TLC toggle mode 2.0 memory which includes a certain amount of single bit memory for write caching purposes, the amount varies depending on the size of the drive ( this is the reason for the better write figures over the 840 ), according to Samsung the memory as the same life expectancy as rival manufacturers of MLC memory, the estimated life expectancy from extensive testing by Samsung is around 3,700 write erase cycles, a step below the Pro. The drive as a 3yr limited warranty. There is little difference between the performance of the Pro and the EVO, performance aside the Pro overall is a better drive especially where there’s a lot of write amplification, as a OS drive the cheaper EVO may be the choice.

Links on SSD Technology
Below are some useful SSD links, with information on how these drives work, there weaknesses and there advantages over conventional drives.
SSD Drive Links.
General information on ssd drives.
SSD vs HDD : This explanation on the major differences and the pro’s and con’s of using either type of drive, all drives have there uses, this short article comes from StorageReview.com. Mar 2014
Understanding SSD’s : Why ssd’s hate write amplification. This is a interesting article by Kent Smith on write amplification, it’s the reason that ssd’s that are written to, with large amounts of data on a daily basis require plenty of over-provisioning or should not be over-filled, if you are going to require more than 70% of a ssd’d space, then you should buy a larger ssd drive or a drive with extra over-provisioning. Here’s the link from Techspot.
Understanding TLC Nand This Anandtech link as become important as cheaper drives will be introduced with TLC memory, The Samsung 840, which will be released in October 2012 will have Samsungs TLC toggle memory. Sept 2013 quality of nand memory over the years as improved cell life considerably, Samsung quotes the average cell life of there TLC as 3,700 writes per cell, I would consider this to be high side.

SSD Endurance Testing.
Added October 2013, these will be links to sights that are testing ssd’s for life endurance, a topic that is of interest to both new users and experienced users of ssd drives.
Introducing the SSD Endurance Experiment ( just how long do they last anyway ? ). This is a experiment started by TechReport in August 2013, the ssd’s being tested are the Corsair Neutron GTX, Intel 335 series, Kingston HyperX 3k, Samsung 840 and 840 pro.
The SSD Endurance Experiment: 22TB Update
Sept 6 2013, This is a update of the TechReport endurance article posted above. The experiment is done using the Anvil ssd software.
The SSD Endurance Experiment: 200TB Update
Oct 28 2013, TechReport testing reaches 200TB mark and first bad blocks begin to appear.
The SSD Endurance Experiment: 300TB Update
Nov 25 2013, TechReport testing reaches 300TB mark, a few more bad blocks but testing shows ssd endurance is better than published statistics
The SSD Endurance Experiment: 500TB Update
Jan 9 2014, TechReport testing reaches 500TB mark, bad blocks continue to increase on the Samsung 840 but testing shows ssd endurance is better than published statistics. 500TB is a incredible amount of writing to any ssd drive, these tests show that with modern ssd drives that optimization in the case of cell life is no longer a issue with quality ssd drives. Reliability is more of a issue especially in the power section and more consistant IOPs with client drives. Read the report, the figures are amazing.
The SSD Endurance Experiment: 600TB Update
Feb 23 2014, TechReport’s testing reaches 600TB mark, the Samsung 840 continues to lose sectors and the other drives only the Intel 335 with the odd bad sector, the remaining drives are intact. The drives have been rested for a few weeks then checked for data retention then it’s on to the 1PB mark.
The SSD Endurance Experiment: Casualties on the way to 1PB Update
Jun 16 2014, TechReport’s testing reaches 1PB with 3 casualties, the HyperX 3K failed at 728TB, the Intel 335 at 750TB and the Samsung 840 (TLC) failed somewhere between 900TB and 1PB and bricked without warning, it seems by these failures ssd drives do not go into read only mode.
The SSD Endurance Experiment: Only two remain after 1.5PB Testing reaches 1.5PB and only two remain with the Neutron GTX failing suddenly at 1.2PB. Sept 24 2014 from TechReport.
The SSD Endurance Experiment: Two Freaking PB's The survivors soldier on to another really big number. Dec 4 2014 from TechReport.
The SSD Endurance Experiment: They are all dead the experiment is finally finished with the Samsung 840 pro expiring at 2.4 PB’s. Mar 12 2014 Techreport
Some Interesting Conclusions:
1. Most drives are not readable when they expire.
2. Some drives expire when the percentage reads 0, the data remains readable.
Drives that last long after the percentage read reaches 0, if they are allowed to
expire the data is lost.
3. Some drives give no warning when they are about expire. Eg the Samsung’s
gave no warnings prior to expiring.
4. There is no reason to worry about how long the nand memory will last, in most
cases these drives will last as long as the drive fails for other reliability reasons.
5. As the drives get older, inactive drives tend to lose their data quicker.
6. No real answers on how long ssd drives will retain data when inactive. Still
question marks about this, eg can you use ssd’s for data disks?
7. Great experiment and well worth reading.

LesT (Toker) as done an excellent job on this relatively new set of optimizations for win7/8, rather than being copied from other sites, Les as put together a more realistic set of tweaks from what he as learned from testing thousands of SSD drives, these tweaks include explanations on why they should be used. Well Done Les.
SSD Migration or Fresh system Installation – An SSD Primer, Read the experts opinion on which method to use, from TheSSDReview. This is one of the guides listed below, it's a question asked repeatedly, there are number of factors in the decision to Migrate or do a fresh install, I've done both without loss of performance or issues. If it's simple to do a fresh install, it's the better option, Migrating or cloning can be difficult for people with limited experience, but if successful, is by far the quicker method. The downside to cloning from HDD to SSD, is the need to manually optimize the ssd drive after completion and reduce write amplification by disabling certain services, on a fresh install, windows 7 will automatically make most of the changes. June 2012.
Change from IDE to AHCI after Windows install This Thread is from the OCZ forum by RyderOCZ. June 2012.
Moving from IDE to AHCI can easily be done by disabling the IDE driver in the win7 registry, then rebooting with the bios set to AHCI, win7 will load it's native AHCI driver, you can change this driver later from within windows 7.
