Product Description

The Plextor 256GB M3S SATA 6Gb/s SSD provides read/write speeds up to 510/360 MB/s in sequential mode and up to 70,000/65,000 IOPS in random mode. The M3S is powered by True Speed which gives it the ability to deliver sustained high performance even after extended periods of continuous operation and years of intensive use.Performance specs of most SSDs are usually based on FOB (Fresh Out of the Box) products, which can result in overstated performance results. Plextor exceeds industry expectations by doing Enterprise Benchmark testing of consumer drives in a Dirty/Steady State to demonstrate sustained Read/Write performance.Each SSD drive is put through the rigors of a 20-hour high temperature burn-in test and strenuous simulations of real-world working environments. This type of testing gives a more realistic perspective of everyday performance. As a result Plextor SSDs have a 0.5% average annual failure rate, which is one of the lowest in the industry.True Speed maintains an extraordinarily high transfer speed rate while maintaining original performance levels in the long term without the severe write speed degradation common with other SSDs. True Speed optimizes data transfer speeds with exclusive firmware featuring Instant Restore, Global Wear Leveling, and Bad Block Management.The M3S is powered by the server grade Marvell 88SS9174 controller chip supporting a SATA III 6Gb/s interface and the highest-quality Japanese NAND flash by flash memory innovator Toshiba. Plextor’s True Speed coupled with advanced firmware and best in class hardware ensures full potential performance even when data is heavily fragmented as a result of prolonged usage.The M3S is the ideal drive for power users, serious gamers, system integrators, and other users who demand fault tolerant performance. (SSD Technology is used by the military and aerospace industries because of its stability and durability.)

From the Manufacturer

The Plextor M3S SATA 6Gb/s SSD series provides read/write speeds up to 525/445 MB/s in sequential mode and up to 70,000/65,000 IOPS in random mode. The M3S features True Speed technology and an extended five year ironclad warranty.

Plextor MS3 SSD
PLextor MS3 SSD
Featuring exclusive True Speed technology for consistent high performance
Built with True Speed Technology

The M3S features exclusive firmware with True Speed, including Plextor's proprietary Bad Block Management, Global Wear Leveling, and Instant Restore technologies that optimize performance.

True Speed is an exclusive technology providing consistent high performance in real-life computing environments for the lifetime of the product. True Speed is designed to prevent drastic drops in read/write speeds that normally occur with SSDs after prolonged use or when data becomes heavily fragmented. True Speed technology will maintain the M3S' high performance and read/write speeds at like-new levels throughout the life of the drive. True Speed distinguishes Plextor SSDs from other SSD products because of sustained read/write speeds throughout the lifetime of the product.

Highest Quality Components for Optimum Performance

M3S drives use a server-grade Marvell 88SS9174 controller chip for read/write speeds of up to 525MB/s and 445MB/s in sequential mode, and 70,000 and 65,000 IOPS for random read/write operations at 4K file size. The M3S supports SATA 6Gb/s and is backward compatible with SATA 3Gb/s and SATA 1.5Gb/s. It also uses the latest 24nm synchronous MLC NAND flash modules from Toshiba to further enhance product reliability. The DDR3 DRAM cache transfers data faster and helps extend lifetime of the drive. Also supported by the flash is a 1.8V power mode, providing the M3S with extremely low-power consumption.

Plextor strives to exceed industry standards with rigorous benchmark testing; before leaving the factory, each Plextor SSD is put through a 20-hour high temperature burn-in test and an intense simulation of real world environments. As a result, Plextor SSDs have a 0.59% average annual failure rate, which is one of the lowest in the industry.

Consistent Speed Levels Even After Intensive Usage

Smart firmware combines three advanced technologies to sustain performance: Bad Block Management, Global Wear Leveling, and Instant Restore. Bad Block Management and Global Wear Leveling optimize the way data is written on the drive and Instant Restore is a technique that overcomes the problem of declining speed after prolonged usage.

The M3S supports advanced functions such as S.M.A.R.T. failure prediction, the TRIM command, NCQ optimization, and superior Garbage Collection to further increase performance and reliability.

This SSD is one of the best out there.
Very fast compared with my Agility 2 SSD. Applications load faster on the Plextor M3S SSD. Though I'm still using SATA II connection coz my X58 SATA III sucks. I'm sure on intel native SATA III connection, this SSD will scream!

I was confused whether I should get this one or the Crucial M4. They both have the exact same controller. But the Plextor M3S has 512 MB cache, while crucial m4 only has 128 mb. Plus this one has a 5-year warranty.
Plextor M3S has faster write speed, as well as higher IOPS.
Tried ATTO Disk Benchmark & I'm getting both read and write at 280 mb/s @SATA II speed with ICH10R.

Note: Get it from newegg. It's cheaper! They had it for $299 last time after promotion code. Even now it's cheaper (1/26/2012). For some reason Amazon keeps ignoring the lower price from other sites. I should have bought newegg GC instead. I bought this for $389 here. Newegg $299, so $90 difference is HUGE!

I can't really knock the drive. It is AMZAZING. Of all of the SSDs I have used (Kingston, Intel, and Plextor) Plextor SSDs are just so much faster for the money. I buy Kingston for economical and blazing performance over a standard HDD, Intel for compatibility and amazing speed with ThinkPad's hit and miss compatibility with SSDs (intermittent HDD initialization on warm boots with Kingston and Plextor), and Plextor for best bang for the buck lightning speed every chance I get. Plextor is my preferred SSD.

The last two Plextor SSDs I purchased (two slightly different models) were both for Thinkpads's (same exact models). One of them works with no issues at all while the other will cause HDD initialization errors. Both systems have the most current firmware; both drives have the most current firmware.

I don't understand why Thinkpad's are so particular about SSDs. But I have never had an issue with an Intel SSD in a ThinkPad. The work around is easy. If you ever reboot your system (for example after installing updates) and get the error, at the error screen just turn the system off and back on again (cold boot it) and the system initializes the drive just fine.

Again, this is not a Plextor drive issue. That same drive has zero issues in a desktop or in the other laptop.

I had wanted a SSD since they came out, but the absurd prices kept me away - until now. The combination of: 1) Price, 2) Storage size, 3) Speed, and 4) Warranty makes this a no-brainer. If you are going to make the change to solid-state, be sure to include this particular drive in the stable. You will end up back here to make your final purchase. As expected, overall responsiveness of my system has dramatically improved. My PC goes from off to google in about 28 seconds. The windows install went very quickly. I am using a relatively old motherboard with SATA 2.0, so keep in mind that I am limited to about half of the speed this drive has to offer. If you are switching your system drive, I would recommend a clean install and fore-go any "system transfer" software. This unit also comes with the 3.5" adapter to fit into desktop cases, which was a nice addition.

My drive died and I needed a new one so I went SSD. I mean why not. Chose this because it was cheap and had the highest speeds at this price point. Before I had a 500gb 5400 rpm drive. It literally quintupled read/write speeds (I don't really know that - but its blazing fast). I am using it in a Macbook pro 2010 model (you'll have to use the mount screws that are on your old hd since the ones the drive comes with don't fit in the mac mounting bracket - which means you'll need a T6 screwdriver). OS X installed in about 10 minutes off of a USB (opposed to generally 45 min to 1 hour). Fast and speedy. Computer boots in 3 seconds. Windows gives it a 7.9 in the Win Experience Index.

People all over the the mac forums are saying to get the Intel 520 series SSD, but those are running around $240 for 120 gb. This one works great at $160 and I doubt you'd notice an 80 dollar difference in speed.

NOTE: If you aren't trying to run OS X on your mac to save space, you have to install OS X first to get the efi update for SATA controller speeds above 1.5 gb/s. The only way I could get it was by installing os x first, but then you can delete os x, and put windows on there.

Hard drive in my notebook was giving me errors after running Windoze for a while. After doing a disk check and then defrag in Windoze, Disk check would find errors and try to repair them. The hard drive would make slight noises sometimes also. Decided to upgrade to a SSD and WOW, After doing a disk clone, the laptop runs like new again with Windoze and Suse Linux 12.1. Boot up time is cut in half. Opening a program is very quick. No drivers were required.
No need to upgrade my 17" Toshiba laptop for a while now. 3+ yrs old and still works fine.
Now I want to upgrade my AMD 8 core 8150's hard drive to a SSD. That has to wait. :-(

I purchased 2 of these SSD's and paired them in raid 0, the performance is phenomenal. I couldn't believe how fast windows 7 64 bit loaded, then I ran the provided benchmark utility and scores are: write speed avg 433.35 max 600, read speed avg 466 max 750. I'm using the onboard chipset for the Asus Crosshair IV Formula/w a Phenom II x6 @ 3.9ghz w.c. 1.8ghz ddr3 Corshair Vengeance 8gb. I benchmarked from windows load to opening firefox and loading google and did it just under 28 seconds. The drive has a very nice looking brushed aluminum casing and is extremely light even for an ssd. Overall I will say for the $$ its worth it. Nice packaging too.
