CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0.3.
When it comes to handling small bity files, the Crucial BX300 just has the edge over the MX500 when it comes to reads but the situation is reversed when it comes to write performance. Looking at the two sets of benchmark results it seems that the Silicon Motion SM2258 controller has no real preference when it comes to the type of data it is being asked to handle.
