OCZ RevoDrive X2 Review: Killer SSD Performance

CrystalDiskMark Performance

CrystalDiskMark is a synthetic benchmark that tests both sequential as well as random small and large file transfers.  It does a nice job of providing a quick look at best and worst case scenarios with regard to SSD performance, best case being large sequential transfers and worse case being small, random 4K transfers.

Synthetic File Transfer Tests

OCZ Vertex LE - 100GB MLC SSD

Fusion-io - 80GB MLC PCI Express SSD


OCZ RevoDrive 120GB

OCZ RevoDrive X2 240GB

The RD X2 can't quite catch the ioXtreme in read performance until we begin to saturate it with IO request at a queue depth of 32 with 4K transfers.  In short the RevoDrive X2 looks a lot like the IBIS in this test, as it did in our previous test runs.  With respect to write throughput, both the RD X2 and the IBIS show strong performance, occasionally besting the Fusion-io ioXtreme in sequential and larger transfers but falling short of the ioXtreme in small file write performance.
