CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V6.02.
There isn't much to split between any of the three Kingston data centre drives (DC500M, DC500R and DC450R) that we've tested when looking at the 4K QD32 T1 test of the CrystalDiskMark benchmark. Comparing the two benchmark result screens it appears that the Phison PS3112-S12DC seems to prefer compressible data when reading 4K data at a QD of 1.
