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.
In our 4-threading 4K random write testing, the drive peaked at 367,460 IOPS at a QD of 16 before dropping back to 363,874 IOPS at the conclusion of the test. Both figures are way behind the official 700,000 IOPS. We did run a quick test at QD32 with eight threads and saw the result rise to 487,426 IOPS, still nowhere near the official figure.
4K Random Write v QD Performance
The drive is consistent in its 4K random write performance at all the tested queue depths, never dropping out of the top 5 in our results charts.
