Plextor M5 Pro Xtreme 256GB SSD RAID Review

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).

The Plextor M5 Pro Xtreme SSD series contains the following models: – Plextor M5 Pro Xtreme 128GB PX-128M5Pro – Plextor M5 Pro Xtreme 256GB PX-256M5Pro – Plextor M5 Pro Xtreme 512GB PX-512M5Pro Whereby the writing performance of this Plextor M5 Pro Xtreme SSD series alters depending on the capacity. A higher capacity of this Plextor M5 Pro Xtreme SSD has a higher write performance. The read performance is specified for all three SSDs with 540 MB/s, the write performance is according to Plextor for the M5 Pro 128 GB SSD 330 MB/s, the M5 Pro 256 GB SSD has 460 MB/s and the M5 Pro 512 GB SSD is specified with 470 MB/s.

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:
