Samsung 980 Pro with Heatsink 1TB Review

We used CrystalDiskMark 8 to test the random performance of the drive at lower queue depths (QD1 – QD8 where most of the everyday workloads occur) using 1 to 4 threads.

Random Reads.

In our lower queue depth, 4K random read tests, the performance increases steadily as the queue depth deepens for each thread. At QD1 the performance ranged from a low point of 21,108 IOPS for a single thread up to 83,001 IOPS for four threads.

At QD8 a single thread Produced 122,399 IOPS (501MB/s), two threads 184,684 IOPS (756MB/s), three threads 289,621 IOPs (1,186MB/s) and finally with four threads, 348,888 IOPS (1,429MB/s).

Random Writes

The write performance climbs smoothly from QD1 to QD2 before levelling off for the rest of the tested queue depths.
