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 M550 will perform the same no matter if the stored/retrieved data is compressible or not:

As we previously saw, the Crucial M550 512 GB SSD will perform according to its official specs in the sequential reading and writing tasks. The drive also reads and writes 512K files fast, and remains fast enough in the random read/writes of small 4K files, mainly in increased queue depths:
