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 performance, the random write test results are nowhere near the official maximum figure of 2,000K IOPS in our four-threaded testing. The drive's performance is pretty consistent from QDs 2 to 32 with the peak result of 491,292 IOPS coming at the QD16 mark. Even though our test results couldn't get anywhere near the official figure, the drive still ranks as the fastest consumer NVMe drive we've seen to date.
4K Random Write v QD Performance Compared.
Gigabyte's AORUS Gen5 10000 drive leads the Gen4 drives by a considerable margin in all the tested queue depths.
