CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v6.0 and 8.0.

In the CrystalDiskMark QD32 T1 test, the Blue SN570 shows an improvement in read performance over the previous Blue SN550 but the older drive has the edge when it comes to writes.

Looking at the two benchmark screens, it's clear that the in-house WD controller doesn't have a preference for the type of data it's being asked to handle. We could also confirm the official Sequential performance figures for the drive, up to 3,500MB/s and up to 3,000MB/s for reads and writes respectively with a best test read performance of 3,618MB/s and writes of 3,199MB/s.

Using the more advanced CrystalDiskMark 8 in its default setting as well as the Peak Performance and Real World profiles saw the Sequential test results confirm the official  3,500MB/s reads and 3,000MB/s writes with the best results of 3,617MB/s and 3,190MB/s for reads and writes respectively.

Similarly using the Peak Performance profile to gauge the 4K performance of the drive we could confirm the official random read maximum of 460,000 IOPS with a test result of 466,033 IOPS. The drive produced a best random write test result of 444,940 IOPS, a little shy of the official maximum of 450,000 IOPS.
