Samsung 980 Pro with Heatsink 1TB 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 performance, the best write performance figure we saw was 290,437 IOPS was nowhere near the official maximum of 1,000,000 IOPS.

4K Random Write v QD Performance compared.

At QD1 the Heatsink version of the drive performs better than the original drive, but as the queue depth deepens this trend reverses.
