CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using V3.0.3., but will be switching to v6.0 shortly so we have added the two CrystalDiskMark 6 result screenshots.

In CrystalDiskMark's 4K QD32 test the WD NVMe Black isn't quite as fast as Intel's latest SSD760p drive. At a QD of 1, though, the 4K Write performance is pretty good at 205.6MB/s. Comparing the default benchmark screen with the 0 fill test, it seems the new WD controller isn't concerned about the type of data it's being asked to handle.
