OCZ RAID-0 PCIe SSD--Speed, Glorious Speed!

Posted on June 13, 2011 By Jeffrey Layton

In continuing with my search for the coolest stuff from Computex 2011, I found an uber-cool PCIe SSD from OCZ, which seems to be doing some pretty cool stuff lately. At Computex they introduced the OCZ Z-Drive, an R4 88 PCIe SSD that has eight (yes, 8!) SandForce SF-2281 SSD controllers in a RAID-0 configuration (the image below is from www.anandtech.com).

Just in case you missed it the first time, this PCIe SSD has eight SandForce controllers in a RAID-0 configuration. The SandForce controllers use real-time data compressions and achieve some pretty remarkable performance particularly in random write IOPS, but now there are no less than eight of these controllers in a RAID-0 configuration. The card is a PCIe Gen2 x8 card

According to the article at Anandtech, there was a demo unit with several of these cards running a 4K random read test that achieved over 1 million IOPS. The drive has specs up to 2.9 GB/s reads and 2.7 GB/s writes (not too shabby but I would really like to see the 4K random write IOPS).

While one should always worry about RAID-0 solutions, SSDs can actually make you breathe a little easier. But man does this card have some serious speed.
