Especially regarding sequential throughput rates the OCZ Revo Drive X2 impressed us. When reading 128 KByte blocks there was a peak in throughput performance of an astonishing 933 MByte/s. On average sequential write and read performance are 671 MByte/s and 812 MByte/s. Therefore you can more or less believe the specs OCZ provides.
Regarding random write and read processes the picture looks a bit different. At this point you can clearly see the influence of the RAID0 configuration. With a junk size of 128K we expectedly saw a peak in performance when testing 128 Kbyte block size. But as soon as one starts looking at 4K or 16K results you see the negative effect the quite relatively large junk size has. In these two tests the Revo Drive X2 should show significantly higher numbers because 40'000 IOPS are only a third of what OCZ writes in their specifications. The same applies to the 10'800 IOPS when performing random read actions. But never the less, we do not want to criticize these results too much because they still are on a very high level.
On one hand the RAID controller with its integrated BIOS makes the installation of the Revo Drive X2 really easy. On the other hand there is the junk size you have to set. If you choose it to be big sequential throughput benefits and if you choose it small random IOPS will be faster. Unfortunately it is not possible to combine both advantages to profit from both, a high throughput as well as very high IOPS. This means that you'll have to decide what you want when you setup the RAID configuration.
