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.
The MP600 Elite with Heatsink is rated as up to 1,200,000 IOPS for writes. As with the random read tests, we couldn't get close to that with our 4-threaded testing, the best we saw from the drive was 416,711 IOPS (1,795MB/s) at QD32.
4K Random Write v QD performance.
At QD 1 the drive is the fastest Gen 4 consumer drive we've seen to date in this test. However, as the queue depth deepens the drive slips down the table but it never drops out of the top 10.
