Crucial T705 2TB 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.

As with the random read results with our four threaded random write tests, we couldn't get close to the official maximum of 1,800K IOPS. The best we saw from testing was 454,432 IOPS at QD4.

4K Random Write v QD Performance compared.

Even though our test results couldn't get anywhere near the official figure, the drive still ranks as the fastest consumer NVMe drive we've seen to date at QD1. But as the queue depth deepens the performance drops back compared to its competitors until at QD32 it sits in last place in the results chart.
