Western Digital Black PCIe Gen3x4 NVMe 512GB SSD Review

CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0.3.


The WD Black PCIe drive lags behind the rest of its peers when it comes to dealing with small bity files at a queue depth of 32 for both reads and writes. At a shallow queue depth, its write performance completely outshines the read.

Comparing the two sets of results, the Marvell controller seems to have no strong preference when it comes to types of data it is being asked to handle.
