4K Sustained Random Read
The official random 4K read figure for the SSD 900P is up to 550,000 IOPs and although we couldn't reach that maximum figure with our tests, the tested 4K read result of 520,584 IOPS is still in the same ballpark.
Intel's 3D XPoint memory is all about producing very high random read performance at low queue depths, where most of the everyday workloads occurs. As you can see from the queue depth result charts, it certainly achieves that aim.
