CrystalDiskMark Testing

CrystalDiskMark is a synthetic test that evaluates 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 hard drive performance, best case being large sequential transfers and worse case being small, random 4K transfers.

CrystalDiskMark tells somewhat of a different story than ATTO. Here, the WD RE4 2TB drive puts up better sequential read and 512K write performance than the new VelociRaptor, but the VelociRaptor still manages to outpace all of the other drives handily.
