Kioxia Exceria NVMe 1TB SSD Review

The official 4K random read performance figures (QD32 T8) for the 1TB model are up to 350,000 IOPS. As you can see from our 4-threaded tests we couldn't match that official figure, the drive producing a peak test result of 214,385 IOPS. However, a quick test of the drive at a QD of 32 with eight threads saw a peak figure of 414,268 IOPS, quite a bit quicker than the official figure.

4K Random Read v QD Performance

The drive performs well at a QD of 1 but as the queue depth deepens,  the 1TB Exceria NVMe begins to fall back.
