Crystalmark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0.3.
Samsung's 500GB SSD750 EVO handles the deeper 4K queue depths of the Crystal Disk Mark benchmark QD32 test pretty well. At a shallow depth it is the same story with strong 4K write performance, but the 4K reads are pretty good too.
Comparing the two benchmark screens it would appear that the MGX controller isn't that fussy about what type of data it handles.
