Intel Optane DC P5800X 800GB SSD Review

Rating: 8.5.

Today's review is no ordinary drive – this unit has been dubbed by Intel as “the world’s fastest data center SSD.” We are of course talking about the Optane DC P5800X, which combines second-generation Optane memory and a PCIe 4.0 x4 U.2 interface, backed by extraordinary endurance.

The Optane DC P5800X is available in just three capacities; 400GB, 800GB (the drive we are looking at here) and the flagship 1.6TB drive. It uses an Intel PCIe 4.0 x4 NVMe Optane 8-channel controller looking after Intel's 2nd generation Optane memory.

Intel quote Sequential performance figures for the 800GB drive as up to 7,200MB/s for reads and up to 6,100MB/s for writes. Random performance ratings are up to 1,500,000 IOPS for reads and up to 1,350,000 IOPS for writes. As an aside, the 400GB and 1.6TB drives are rated at the same 7,200MB/s for Sequential reads with the smaller drive rated at up to 4,800 MB/s for Sequential writes while the flagship 1.6TB drive is rated at up to 6,200 MB/s. Random reads for the 400GB and 1.6TB drives are stated as up to 1,500,000 IOPS and writes at up to 1.150,000 IOPS and 1,500,000 IOPS for the 400GB and 1.6TB drives respectively.

Intel quotes an active power rating for the 800GB DC P5800X of 18W, and 4.2W when idling. The endurance ratings for the drive are out of this world. The 800GB P5800X is rated at up to 100 DWPD, that's a 100 drive writes per day – for the length of the 5-year warranty
