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 1,500K IOPS in our four-threaded testing. The drive's performance is pretty consistent from QDs 2 to 32 with the peak result of 486,798 IOPS coming at the QD16 mark before finishing the test run at 485,696 IOPS (QD32).
4K Random Write v QD compared.
Crucial's T700 tops the chart at QD1 but as the queue depth deepens, the other Gen 5 drive, the Gigabyte AORUS Gen5 10000 takes over.
