CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V6.0.0. to test HDD drives.

In the CrystalDiskMark 4K QD32 T1 test, the 20TB WD Red posted the best read score to date for a mechanical hard drive of 3.651MB/s. Its write performance of 4.568MB/s is also impressive but is some way behind the other 20TB WD drive we've recently reviewed, the enterprise focussed Ultrastar DC HC560.
