The M6S comes in an eye catching, yellow and black box. Along with a picture of the drive, the front advertises a number of its key features including its 256GB capacity and support for Plextor's True Speed technology. The back of the box provides a bit more information regarding its features and specifications.
Plextor doesn't include a lot of extras with the M6S. Aside from the SSD, the only other thing in the box is a small, fold out guide containing warranty information as well as some brief installation instructions for both desktop and notebook computers in a number of different languages.
Like Plextor's previous SSDs, the M6S is very well constructed. The drive's outer casing is made entirely out of metal. Along with it being strong and durable, it is very lightweight. On top of that, its brushed aluminum finish looks great.
Plextor has reduced the M6S's height from the standard 9.5mm down to 7mm. While that doesn't sound like much, this ultra-slim form factor lets you install the drive in ultrabooks as well as standard laptops and desktop PCs.
Like the M6M, the M6S 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 biggest difference is that instead of eight NAND flash channels, the 88SS9188 supports only four.
For the PX-256M6S, Plextor has opted to use Toshiba's A19nm TH58TEG8DDKTA20 Toggle Mode MLC NAND flash modules. Looking at the pictures above, you can see that there are eight of these 32GB chips on top of the PCB. The drive also has a single 512MB SK hynix H5TC4G63AFR DDR3 memory chip that is used for caching and garbage collection.
