The official 4K random write rating for the Rocket 4 Plus is up to 700,000 IOPS. As you can see from our 4-threaded test results we couldn’t get close to that figure, the best we saw was 257,546 IOPS at QD32. We did a quick test at QD32 using 8 threads and saw the IOPS figure rise to 607,772, a lot closer to the stated maximum figure.

4K Random Write v QD Performance compared.

At QD1, the 2TB Rocket 4 Plus tops the results chart at 173,538 IOPS. After this point, it slowly drops down the charts as the tested queue depth deepens.
