Plextor M3 / M3S 256GB Solid State Drive Review

Plextor M3 Series 256GB SSD




Here we get our first look at the Plextor M3 Series 256GB SSD. There isn't much going on with the top side other than the silk screened Plextor logo.




On the back we found the serial, model and product number. The four mounting points are also where they should be.




This is a 2.5" form factor drive with a 9mm height. The side mounting points are where they should be as well.




The SATA power and data connectors are offset to the side of the drive so you won't have any issued installing this drive in your notebook. The included desktop adapter bracket offsets the drive so even when used in a 3.5" bay the SATA power and data connectors line up with your standard 3.5" form factor drives.




We've seen this PCB design before on the Corsair Performance Pro. On one side we found the Marvell 88SS9174-BKK2 flash processor unit. This is an ARM based controller that can be programmed via firmware to emphasize performance in key areas differently. The BKK2 is a very robust controller that is being used in several SSDs at this time.




The 256GB capacity size PX-M3S uses 512MB of DDR3 DRAM for cache and to hold page location data. Here we also see the 24nm Toshiba Toggle Mode flash which is unique to the Plextor M3 Series at this time.




The M3 also uses thermal transfer pads to aid in keeping the internal components cool. These also help with shock, acting as buffer pads if a drive is dropped.
