OCZ Z-Drive R4 PCIe SSD Performance Preview
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 larger sequential transfers and worse case being small, random transfers.

The song remains the same, to quote a Zeppelin title. In sequential and large transfers, the Z-Drive R4 rips every other competitive score to shreds. In small 4K random transfers, the R4 shows competitive write throughput but comes up short in reads versus the Fusion-io card, again with light duty workloads and queue depths. At the 4K and 32 queue depth setup, the Z-Drive R4 drops in behind the more expensive SLC NAND-based LSI WarpDrive, but keep in mind the IOMeter scores you saw earlier. As queue depth scales, the Z-Drive R4 will pull ahead of other solutions rather quickly and by large margins.
