Compared to the bright yellow box that Plextor's M6S series SSDs come in, the M6M's packaging is pretty boring. The drive ships in a simple clamshell similar to what memory modules come packed in. The sticker on top shows the model, capacity, firmware version and serial number of the drive inside. It's hard to make out in these pictures, but Plextor has also managed to squeeze in the drive's specs. Inside the packaging, you'll find the drive as well as a bag containing a couple of mounting screws.


Physical Features:

The M6M follows the JEDEC MO-300 standard for mSATA SSDs. It measures a mere 50.8 x 29.8 x 3.6 mm and is about one-eighth the size of a standard 2.5-inch drive. The M6M also has a 52-pin mSATA connector which supports data transfer rates up to 6 Gb/s.

Like the M6S, the M6M uses Marvell's 88SS9188 "Monet Lite" controller. There is very little information available regarding this controller but from what we can gather from our conversations with Plextor, it is very similar to the 88SS9187 "Monet" controller found in the M5M, M5 Pro and M5Pro Xtreme. The main difference is that instead of eight NAND flash channels, the 88SS9188 supports only four.

For the PX-256M6M, Plextor has opted to use Toshiba's 64GB A19nm TH58TEG9DDKBA8H Toggle Mode MLC NAND flash chips. Looking at the pictures above, you can see that there are two of these chips on either side of the PCB. The drive also has a single 512MB NANYA NT5CC256M16CP-DI DDR3-1600 SDRAM chip that is used for caching and garbage collection.
