The Plextor M5Pro Xtreme is a professional SSD designed for business and advanced users who demand high performance, reliability, and true data integrity. It uses the latest Marvell 88SS9187 controller and this provides it with random read / write speeds of up to 100,000 / 88,000 IOPS. Even under heavy loads the multi-core controller and exclusive Plextor firmware make the M5Pro Xtreme extremely fast, reliable and stable.

Multi-Tasking and Ultra-High Performance

The combination of the latest Marvell 88SS9187 controller and the best quality Japanese Toshiba Toggle NAND flash creates M5Pro Xtreme with enterprise-class performance. It has the ability to consistently deliver random read / write speeds up to 100,000 / 88,000 IOPS and sequential read / write speeds up to 540 / 470 MB/s. This makes the M5Pro Xtreme suitable for use in a heavy workstation, server role, or Raid 0 configuration.

Benchmark Results: PCMark 7 & Iometer 2008

M5Pro Xtreme’s high score means the best and most stable overall performance.

The drive also makes use of True Speed technology, which prevents the drastic performance drops seen in some SSDs after intense or long-term usage.

In line with the needs of advanced users for data integrity and confidentiality the M5Pro Xtreme offers a unique enterprise-grade double-data protection technology. Using latest 128-bit error correction system built into the latest Marvell controller it is able to automatically check and correct the accuracy of data being read from the Flash memory. This is complemented by a second layer of read protection offered by the Robust Data Hold-out algorithm in Plextor’s exclusive firmware, allowing the drive to achieve total data accuracy even in the long-term.

For data confidentiality the M5Pro Xtreme supports full drive encryption with an Advanced Encryption Standard (AES) 256 bit algorithm using its US Government AES-validated Marvell controller.

The combination of the latest Marvell 88SS9187 6Gb/s SATA controller’s powerful 128 Random Bit/2K BCH ECC, the exclusive Plextor firmware and the Robust Data Hold-out Algorithm gives the M5Pro Xtreme unequaled data integrity.

True Protect ensures that data is stored and retrieved without error by using ECCs, Plextor Firmware and Robust Data Hold-out Algorithm.

AES is the U.S. government standard encryption technology, it is divided into three levels 128,192, 256 The Plextor M5Pro Xtreme 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.


With the M5Pro Xtreme, Plextor has focused on developing and supplying one of the most stable drives on the market. To achieve this, extensive pre-production testing took place using the world’s most advanced SSD testing facilities - FLEXSTAR testing chamber. It was only when the design was able to pass strict enterprise-grade Zero Error standard of 400 units surviving 500 hours of the toughest continuous testing without a single error or failure that the drive was approved. To ensure stability and reliability for individual drives all drives undergo rigorous high-temperature burn-in tests and accelerated usage simulation testing.

Preproduction tested for professional use in Plextor’s state-of-the-art testing facilities. Rigorous operational and environmental tests resulting in drive with an impressive MTBF of 2.4 million hours.

  • 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.


The Plextor M5Pro Xtreme’s high build quality is backed by an iron-clad 5-year warranty from Plextor for total peace of mind. An extensive technical support system will provide support throughout the drive’s long life and make the M5Pro Xtreme a performance upgrade that you can have total confidence in.



"Two new technologies in one very rapid drive and it still comes in under the £1 per GB barrier."


"Read speeds are the fastest we have seen to date. And although OCZ's Vertex 4 capped our write benchmarks, the M5 Pro is unique in the speed and consistency of its write performance. The Vertex 4 can't match it there."


"We can basically write the same conclusion for the Plextor M5 Pro 256GB as we did for the 128GB model. It's the fastest SSD in its category."
