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, we couldn't get close to the official maximum of 1,400,000 IOPS using our four threaded tests. The best we saw was 414,777 IOPS at QD16. After this peak, the performance dropped slightly to finish the test run at QD32 at 409,745 IOPS.
4K Random Write v QD compared.
As with the random read result, the QD1 random write performance of the MP700 Elite with Heatsink is very impressive, outperforming all of the high-end drives in this list. Unfortunately, it doesn't maintain this position as once the queue depth deepens the performance of the drive compared to the rest of the Gen 5 drives here drops off and the drive drops to last place on the charts
