4K random read has the WD Black starting with 175 IOPS at QD1 and finishing just shy of 400 IOPS at QD32.

Rather surprisingly, the WD Black does not lead the charts when it comes to 4K random write. In fact, another WD drive leads in the area, the WD Red.

 

However, performance is consistent across the entire QD range.
