Reviews Word on the street for the Plextor PX-256M5S

The PX-256M5P is the first SSD to use Marvell's 88SS9187 SSD controller, and it packs a bevy of high-end capabilities.

What People Are Saying Give it to me straight


Its random read/write performance is significantly better than some of the other SSDs we've tested, but it's also more expensive.

With multiple drives slipping well below the $1/GB mark, Plextor may trim prices sooner rather than later.
by PCMag (Nov, 2012)


Plextor claims the M5 Pro can hit read speeds of up to 96,000 IOPS and sequential read/write speeds of 5 40MBps and 450MBps, respectively.

The company first made a name for itself in the early days of CD and DVD burning, when the quality of drives and blank media could vary enormously from company to company.
