Kioxia Exceria Plus 2TB NVMe SSD Review

The official 4K random read figure for the drive is up to 680,000 IOPS, this figure is from the drive being tested at a QD of 32 using 8 threads. With our 4-threaded tests, we couldn't get close to this figure, the best we saw was 329,570 IOPS at a QD of 32.  We did a quick test using 8 threads at a QD of 32 and the best we got from the review drive was 517,506 IOPS, still a fair way off the official maximum figure.

4K Random Read v QD Performance

The drive performs best at QDs 2 and 4 but drops away from a good many of its competitors at QD's 1 and 32.
