Samsung SSD 980 1TB Review

In our 4-threaded random read test, the drive peaked at 250,960 IOPS (1027.93MB/s). Samsung quote two 4K random read figures for the drive, up to 17,000 IOPS at QD1 using a single thread and up to 500,000 IOPS at QD32 using 16 threads. Our 4-threaded test results sit comfortably between the two official figures.

4K Sustained Random Read v QD comparison.

At QD1, the drive is the third-fastest we've seen to date but as the tested queue depths deepen the drive sinks further down the result's charts.
