Plextor supplies the M5S inside a very simple, serious looking box. The company has never been big on marketing and the box reflects that as well. As the M5S is a value-oriented product, there is no desktop mounting kit or anything else included with the disk.
The M5S is a simple, elegant device. It has a steel chassis, brushed to give it a hard, metallic appearance, with rounded corners. The logo of the company can be seen at the top right side of the disk.
Plextor painted and treated the bottom of the disk as well, unlike many other companies which leave the bottom plate unpainted or even full of scuffs. The usual sticker with the barcode, certifications and basic data of the drive can be found there.
After cracking the SSD open, we revealed a full size PCB with 8 memory chips, the controller and a single 256MB RAM cache chip.
Plextor based the M5S on the Marvell 88SS9187-BLD2 controller, the best controller from Marvell currently available, which is very strange for a value-oriented product. Plextor compiles their own firmware for their SSDs, including the M5S.
The memory chips are synchronous type, supplied by Toshiba. These are considered to be very advanced and high quality products which, once again, makes us wonder what they are doing in a product designed with value in mind.
Finally, Hynix is the supplied of the 256MB DDR3 RAM chip, which the controller is using as cache.
