4K Random Read v QD comparison

To give an idea of how powerful Intel’s 3D XPoint memory technology is at low queue depths for random read performance, here we show the Optane DC P5800X up against a fast Gen4 NVMe desktop drive, in this case, Corsair's 2TB MP600 PRO XT. At QD1 the Corsair drive is running at 20,176 IOPS, the DC P5800X is over twice as fast at 74,875 IOPS both using a single thread. However, at QD8 both drives are running at around the same rate, with the exception of the three threaded performance where the Intel drive still has the edge. Also, note the huge difference in the latency figures at QD1.

Random Write v QD comparison

~

It's a much closer affair when it comes to random writes, with none of the huge performance differences between the two drives seen in the random read comparison.
