Crucial M4 SSD 128GB Review

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.

Again, the benchmarks clearly show that Crucial’s claim of 500MB/s sustained transfer speed and 175MB/s sustained write speed are validated.
