We used CrystalDiskMark 8‘s custom settings to test the 4K random write performance of the drive through a range of queue depths.
In our random write tests, we couldn’t get close to the official maximum figure of 800,000 IOPS (QD32). The best figure we saw was 368,799 IOPS at QD8.
4K Random Write v QD Performance compared.
Our best 4K random write result may not be anywhere close to the official figure but the only tested QD where the drive doesn’t top our result charts is at QD2 and even then it’s in second place.
