We used CrystalDiskMark 8‘s custom settings to test the 4K random write 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.
As with the random read results with our four threaded random write tests, we couldn't get close to the official maximum of 1,500K IOPS. The best we saw from testing was 451,618 IOPS (1,849MB/s) at QD32.
4K Random Write v QD performance compared
Unlike the random read results, when it comes to random writes, the drive stays in the bottom spot for all the tested queue depths.
