CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v6.0.
The DC500M has slightly better write performance than the DC500R in the CrystalDiskMark test at a QD of 32. Comparing the two benchmark results it appears that the Phison PS3112-S12DC seems to prefer compressible data when reading 4K data at a QD of 1.
