CrystalDiskMark is another benchmarking utility that determines speeds by measuring 512KB, 4KB, and 4KB (Queue Depth 32) sequential and random read and write speeds. Test data can be Random, 0Fill, and 1Fill. For our purposes, we left the test at Random.
CrystalDiskMark demonstrates that the OCZ Vector is able to sustain transfers at a much higher write speed than that of the Crucial M4. The Read speeds are almost identical between the drives with a slight edge to the Vector.
