Plextor M5S Packaging

Plextor M5S Packaging

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.

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.
