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 Read

At QD1 the performance of the 1TB WD Blue SN580 ranges from a lowly 20,110 IOPS (82MB/s) using a single thread up to 69,199 IOPS (283MB/s) using four threads. The performance increases steadily as the queue depth deepens for each thread count.

Random Write

When it comes to random writes, there is a noticeable sharp rise between QD1 and QD2 with the three and four-threaded tests. Although the performance keeps increasing as the queue depth deepens, the rate of increase isn't as sharp.
