The Plextor M5M is a high-performance mSATA 6 Gb/s SSD specifically engineered to give ultra book, tablet PC, and other JEDEC MO-300 form factor users the speed and low power consumption benefits of the newest generation SSD technology.

  • - Latest server-grade Marvell® 88SS9187 controller ensures fast and reliable operation for all applications.
  • - Sequential mode performance of up to 540MB/s read and up to 320MB/s write, boosts the responsiveness of ultra-thin laptop and tablet PCs.
  • - Random read speeds of up to 80K IOPS and write speeds up to 76K IOPS at 4K file size, give maximum real-world performance benefits.
  • - Advanced True Speed technology provides long-term sustained performance for all data types and prevents speed drop.

Plextor SSD has a unique True Protect protection system to protect the integrity of your data. To confirm that each piece of data is correctly stored with one hundred percent accuracy the newest 128-bit error correction code is used. For data confidentiality, the drive uses hardware in the US Government AES-validated Marvell controller to provide secure 256-bit full-drive encryption.


The combination of the latest Marvell® 88SS9187 6Gb/s SATA controller’s powerful 128 Random Bit/2K BCH ECC (Error-Correction Codes), and the exclusive Plextor firmware based Robust Data Hold-out Algorithm gives the M5M unequaled data integrity.


AES, the U.S. government standard encryption technology, is divided into three levels 128, 192, 256. The Plextor M5M uses the highest level of encryption-256 bits. This level of SSD encryption is highly secure compared to BIOS or software based encryption and offers strong protection if the computer is stolen.

  • Supports the SATA Device Sleep standard incorporating the new DEVSLP state allowing the SSD to communicate in sleep mode.
  • With the DEVSLP mode, the M5M can reduce the power consumption to only 1 mW, and resumes from DEVSLP mode only in 100ms.
  • In order to meet the needs of consumers, the M5M delivers an effective operating and long battery life of the mobile device.

48hr Sustained Read and Write Test
Two days continuous 4K file read/write test, zero error pass requirement.
4000 Times Idle Test–Sleep and Hibernation Test
After 24 hrs read & write SSD enters sleep (S3) mode and is woken after 5 minutes, repeated for hibernation (S4) mode, zero error pass requirement.
250 Times Power Cycle–Cold and Warm Boot Tests
Continuous cold boot and warm boot cycles 250 times, zero error pass requirement.

With its ultra mini size, light weight and low power consumption, the M5M is especially suitable for ultra-portable on-the-go computing device..

  • - Highly compact JEDEC MO-300 form factor incorporating an mSATA 6GB/s connection.

5 out of 5 eggsSo far so good!

Pros: It was a great price when I got it. Easy installation, simple packaging. I haven't had it for long, but I purchased the 1 year extended replacement plan, so I'm sure I will be ok.

Cons: Didn't come with a screw, but that's not an egg subtracting issue. I just robbed peter to pay paul, taking a screw out of my work laptop lol. I can replace that from extra parts at work, since I work in IT for a hospital.

Other Thoughts: Could make me breakfast.

5 out of 5 eggsPerfect for my Vostro 3560

Pros: Fast! I'm using Windows 7 Pro and it takes about 15 seconds for the computer to boot up to the log on screen. All of my programs, such as Word and Outlook load extremely fast. Photoshop loads in 2 seconds!

Cons: Nothing that I came blame on Newegg or Plextor. The only issue is that I had to dismantle my notebook to install the device, so that's an issue with Dell.

Other Thoughts: I use my notebook for business, so I have a mechanical drive to store emails, documents, pictures and other data. If you're concerned about writing cycles, no worries. There are things you can do to limit them. I moved the SoftwareDistribution folder, which is where Windows 7 updates are saved, to the mechanical drive and redirected Windows to that folder (search Google). I also moved the cache for the web browser and data files for Outlook to the mechanical drive.

5 out of 5 eggsLove It

Pros: Cool factor, it's so tiny and plugs into the M-sata spot on my mobo. It's still working and it's fast, 20 secs to useable desktop.

Cons: Cost per megabyte

Other Thoughts: If your motherboard has an m-sata slot these are so cool.

3 out of 5 eggsmine show as SDHC card

Pros: Small and a decent price

Cons: Have not gotten it to work properly yet

Other Thoughts: I was excited that my new laptop had a slot for this. Hoever, it shows up as a SDHC card in my computer under windows 8.

I had made an image of my hard drive and restored it to this msata and it didnt boot. Im not sure what im doing wrong.

has any one else had this issue. I do this stuff all the time and I am stumped.
