Intel Optane DC P5800X 800GB SSD Review

Intel rates the 800GB Optane DC P5800X at up to 1,500,000 IOPS for random reads. We couldn't get anywhere close to that figure with our 4-threaded testing with the drive peaking at 368,804 IOPS at QD8 before dropping back slightly to finish the test run at 347,976 IOPS (QD128). Intel’s 3D XPoint memory technology has been designed to offer very quick performance at low queue depths and at low latencies at to this end, the QD1 figure of 205,373 IOPS is stunning.

As with the random read testing, when it came to random writes we couldn't get close to the official maximum of 1,350,000 IOPS. The best we got from our four-threaded testing was 312,670 IOPS at QD32. Again the QD1 figure of 184,698 IOPS is very impressive.
