4K Sustained Random Read Performance

The maximum 4K random read figure quoted by WD for the 500GB Blue SN500 is 275,000 IOPS at a Queue Depth of 32 with just a single thread. The review drive produced a tested figure of 176,518 IOPS at QD32 with four threads.

Considering the drive uses an x2 PCIe interface, it comes as no real surprise to see it positioned on or near the bottom of the random read result graphs.
