CrystalDiskMark is a synthetic benchmark that tests 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 SSD performance, best case being larger sequential transfers and worst case being small, random access and transfers.
CrystalDiskMark does a really nice job of exploiting the strengths and weaknesses of the Micron P320h. Here again we see strong Read performance, especially as queue depths increase. Shallow queue depths and small write transfers tend to be the drive's shortfall, however.
