CrystalDiskMark is another synthetic test we've started looking at 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 SSD performance, best case being large sequential transfers and worse case being small, random 4K transfers.
Taken in aggregate, CrystalMark's test suite paints a confusing, contradictory picture of SSD performance. The Crucial C300 performs quite well in the sequential and 512K test, but falls away from the group during the 4K benchmarks. In the 4K Queue 32 test, the C300 splatters with a sound like dead whale chunks falling to the ground.
Results fluctuate between the OCZ Revo, the F100, and the Phoenix Pro. The differences between the GSkill and the Corsair drives mainly shows up in the write benchmarks but the performance gap between the two varies greatly depending on the test.
The Revo still leads the majority of the tests but its 512K write performance was only modestly higher than the SF-1200-equipped SSDs. 4K tests proved especially problematic; the Revo fell well behind the F100 and the Phoenix Pro. The 32-queue 4K tests were a different story—the Revo had no problem outclassing its opponents, although again, the write performance increase was modest. The C300 performed exceptionally well, here, far outpacing the other two drives.
