Review: Plextor M6M 256GB mSATA SSD

Marvell 9188’s First Appearance


At CES earlier this year, one of the SSD vendors with a lot to show off was Plextor who had a number of new SSDs planned for early 2014. Among the SSDs they showed were the Plextor M6e, a M.2 form factor PCIe SSD, the Plextor M6S, a new 2.5″ SATA 6Gb/s SSD, and the Plextor M6M, a new mSATA SSD. So far, we’ve already had a chance to check out Plextor’s first M.2 SSD aimed at the retail market, the Plextor M6e, and was highly impressed with the drive, so now we focus our attention to the the rest of Plextor’s lineup coming out this month.

The rest of the Plextor M6 lineup includes the Plextor M6S and the Plextor M6M which are virtually identical drives with the exception that the M6S is in the 2.5″ SATA form factor while the Plextor M6M is in the mSATA form factor.  Plextor is also planning to launch a M6 Pro, which will be the flagship 2.5″ SATA form factor drive sometime later this year.

That said, today we’ll be reviewing the Plextor M6M 256GB SSD. As far as components go, the Plextor M6M/M6S is controlled by the Marvell 88SS9188 (Monet Lite) controller, which is a controller we’re seeing on our test benches for the first time today along with some of Toshiba’s latest 2nd generation 19nm Toggle Mode MLC NAND.

Without further ado, let’s take a closer look at the Plextor M6M!
