Sustained high-performance, tested long-term reliability and double data protection

The Plextor M5Pro 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 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 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 suitable for use in a heavy workstation, server role, or Raid 0 configuration.

Benchmark Results: PCMark 7 & Iometer 2008

M5Pro’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.

Data Safe

Enterprise-Grade Double-Data Protection

In line with the needs of advanced users for data integrity and confidentiality the M5Pro 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 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 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 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.


Professional Quality and Reliability

With the M5Pro, 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.

Full Five-Year Warranty

The Plextor M5Pro’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 a performance upgrade that you can have total confidence in.


The SSD Review

"The Plextor M5 Pro Xtreme has earned a solid recommendation as one of the better SSDs we have tested to date, an SSD that can definitely be spoken of as a top tier SSD and has earned our Gold Seal."


"In terms of performance there was a lot to like about the M5 Pro, in reads it is exceptionally fast and competes with the fastest SSDs around. Writes can be a little lower on synthetic tests but when it comes to real world use the M5 Pro excelled, especially in larger file transfer operations."

Tom's Hardware

"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."


"The incredible performance, the good warranty conditions and excellent track record of both Marvell and Plextor make this an excellent product. It earns the Hardware.Info Gold Award."
