4K Random Read v QD Performance

Samsung quotes two queue depth figures for 4K random read performance. At QD1 the drive is rated as up to 19,000 IOPS and at QD32 up to 600,000 IOPS. In our tests we comfortable beat the QD1 figure at 48,028 IOPS but the review drive fell well short of the maximum official figure, producing 404,351 IOPS when tested.

4K Random Read Performance Compared

Throughout the tested queue depths, the new drive out-performed the 2TB version of the older SSD970 EVO.
