CrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers using incompressible data. It provides 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 OCZ Vertex 460 offered middling performance according the various CrystalDiskMark tests. OCZ's new drive trailed the pack in the basic 4K transfer test, but came back strong in the 4K QD32 test. The drive fared much better in the 512K and sequential transfer tests, however, and was tightly grouped with the other OCZ drives and the Samsung 840 EVO.
