Kingston NV2 1TB SSD Review

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.

When it came to random writes, the best figure we saw came at QD32 at 270,988 IOPS (1,109.97MB/s). At QD8 the performance drops off (232,079 IOPS) but recovers back by QD16.

Random 4K  write performance v QD compared.

The drive offers pretty consistent performance at QDs 1 & 2 but as the queue depth deepens the drive begins to drop down the results graph.
