We used CrystalDiskMark 8‘s custom settings to test the 4K random read performance of the drive through a range of queue depths. The setup for the tests is listed below.

Transfer Request Size: 4KB, Outstanding I/O: 1-32.

Using our 4-threaded test results, we couldn't get close to the official maximum random read figure of 1,300,000 IOPS; the best we saw was 506,688 IOPS at QD16 before the performance dropped back to 500,221 IOPS at the end of the test run at QD32.

4K Random Read v QD performance compared

At QDs1 and 2, Kioxia's Exceria Plus G4 is the second-fastest Gen5 consumer drive we've seen to date for this test, and it's the fastest E31 T-based drive we've seen at these queue depths. However, at QD4, the drive dropped to last place in the results chart, and at QD3,2 it recovers slightly.
