4K Random Read v QD Performance

The official 4K random read figure for both versions of the 1TB SN750 is up to 515,000 IOPS. Under our tests the drive got nowhere near the official maximum figure. However the drive performs very smoothly as it climbs through the various queue depths.

4K Random Read QD Performance

The Heatsink Edition of the drive is a little faster than the standard drive at a QD of 1. However at QD's 2 & 4 it slips behind the standard SN750 before overtaking it again at a QD of 32.
