plextor_m5_pro_xtreme_256gb_ssd_raid0_1

We recently reviewed one of the fast Plextor M5 Pro Xtreme 256 GB SSD, but we wanted it faster again. Said and done, because today we test two of these fast Plextor M5 Pro Xtreme 256 GB SSDs. We build a hardware RAID0 striping with two of these SSDs and compare their performance with a software RAID 0, with one single Plextor M5 Pro Xtreme 256 GB SSD and with two Crucial m4 SSDs in RAID 0. Let us continue to see, how fast two Plextor M5 Pro Xtreme 256 GB SSDs are in RAID 0.

Thanks for the support …

Many thanks for the support with both Plextor M5 Pro Xtreme 256GB 2.5″ SSD by the manufacturer Plextor.

The Plextor M5 Pro Xtreme 256GB SATA3 2.5″ SSD PX-256M5Pro has at present a price of approx. 199 Euro (05/2013).

On the flipside you can see the label of the Plextor M5 Pro Xtreme SSD with some technical data and the pre-installed firmware version. You can also see the SATA3 connectorss for data and power on the left side. These connectors are identical to conventional SATA3 hard disks and these SATA3 SSDs can also operate with a slower speed at an SATA2 interface:

Here you can see eight out of a total of sixteen 19nm NAND modules of the SATA3 SSD with a total of 256 GB capacity, the 512MB cache module and the new Marwell 88SS9187-BLD2 controller IC. The SSD also provides a built-in 256-bit AES encryption:
