Crystalmark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0.3.
The M7V's 4K write performance is pretty solid although the 4K read performance is nothing to write home about. It also handles deeper data queue depths for read and write's pretty well too.
As can be seen from the two CrystalDisk Mark test scores the controller isn't really that fussed what type of data the drive is presented with.
