The Plextor 128GB M5M mSATA SSD ships in a clear plastic container, tough enough to protect the little drive during shipping. The drive inside measures only 50.8mm x 29.8 mm x 3.6 mm (WxDxH)
The tiny drive is using the Marvell 88SS9187 dual core controller. Plextor vary the DRAM cache according to the capacity – in this case 256MB DDR3. Power consumption is rated at 0.2W when active.
Plextor have placed the controller and two of the four Toshiba 19nm Toggle Mode NAND chips on the top of the PCB. The company claim the drive supports the SATA DEVSLP standard – great news for laptop lovers. The M5M idles down to 1mW and rescales to 200mW within 100ms.
The other side of the PCB houses two more chips and the 256MB DDR3 DRAM cache, branded Hynix.
