It's only 750GB - but it will set you back over £2250. 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.
