The next benchmark is the CrystalDiskMark. The software provides throughput data based on sequential reads and writes, and random (512K/4K/4KQD32) reads and writes of various sizes.

Below you see the drive's performance with incompressible (0Fill) data:

As you see below, the MX200 500GB SSD performs the same no matter if the stored/retrieved data is compressible or not:

As we previously saw, the Crucial MX200 500 GB SSD did not reach its sequential read and write figures quoted by Crucial, although it remained close to those targets. Random writing of small 4K files was surprisingly high (142 MB/s), as well as random writing of 512MB files (453.5 MB/s). The drive was also fast in 4K QD32 files in both read and write tasks. Generally, the MX200 500GB did not exceed the already very good performance of the MX 100 512GB model.
