Today we go hands on with Intel's Optane SSD DC P4800X enterprise-class NVMe drive that uses Intel's 3D XPoint memory technology designed for use in data centres. It's only available in two capacities, 350GB and 750GB, and two formats – a 2.5in 15mm U.2 drive, and a HHHL AIC. For this review we are looking at the 750GB U.2 version.

Loaded with Intel's 3D XPoint memory together with a 7-channel controller, the official quoted Sequential performance figures for the 750GB drive are up to 2,500MB/s for reads and up to 2,200MB/s for writes. The 350GB drive has reads of up to 2,400MB/s with writes up to 2,000MB/s

Random 4K figures are up to 555,000 IOPS for both reads and writes (these figures are for 100% span tests). The 350GB drive has the same read figure but with up to 500,000 writes.

Intel quotes an active power rating for the 750GB P4800X of 18W, and 6W when idling.

Needless to say, a drive aimed at data centres needs some pretty cast iron endurance figures and the P4800X doesn't disappoint. It's rated at 30DWDP, which works out to around 41PBW (yes that's petabytes) over the length of the 5-year warranty Intel backs the drive with.
