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.
From QD2 up to QD32 the performance of the drive levels out, with a peak of 313,446 IOPS at QD32. As with the random read results, this is nowhere near the official 1,300,000 IOPS maximum write figure.
4K Random Write v QD Performance
At QD 1 & 2, the P44 Pro is the fastest-performing 1TB class consumer drive we have seen to date when it comes to random writes. However as the queue depth deepens the performance does drop off so when it comes to the QD32 result, the drive is sitting in the middle of the results chart.
