When Intel first introduced their Optane Memory technology it was as in the form of small SSD's with the primary aim of boosting the performance of SATA based drives through SSD caching. The latest incarnation of the technology, the Optane Memory H10, takes this idea further on by combining Optane Memory technology with the latest QLC 3D NAND on a single PCB.

Currently there are three models in Intel's Optane Memory H10 range with varying sizes of Optane memory and QLC (quad-level cell) 3D NAND combinations. There is a single 16GB model that combines 16GB of Optane memory and 256GB of QLC NAND and two 32GB models, one with 512GB of QLC NAND and a flagship 1TB QLC drive.

The official Sequential performance figures for the 512GB version of the H10 are up to 2,300MB/s for reads and up to 1,300MB/s for writes. The 1TB drive is rated at up to 2,400MB/s and 1,800MB/s for read and writes respectively while the entry 250GB model is up to 1,450MB/s for reads and 650MB/s for writes.

Random 4K figures for the 512GB drive are up to 320,000 IOPS for reads with writes coming in at up 250,000. These figures were achieved using an 8GB span. The 1TB drive is rated as up to 330,000 IOPS for reads and 250,000 for writes while the 250GB drive figures are up to 230,000 IOPS and 150,000 IOPS for reads and writes respectively.

Endurance figures for the range are up to 75TBW for the 16GB/256GB model, up to 150TBW for the 32GB/512GB model with the 1TB drive rated at up to 330TBW. Intel back the H10 modules with a 5-year warranty.

Intel Optane DC P4800X 750GB SSD Review https://www.kitguru.net/components/ssd-drives/simon-crisp/intel-optane-dc-p4800x-750gb-ssd-review/ https://www.kitguru.net/components/ssd-drives/simon-crisp/intel-optane-dc-p4800x-750gb-ssd-review/#respond Wed, 30 Jan 2019 11:09:21 +0000 https://www.kitguru.net/?p=399294 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.

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.

Physical Specifications:

  • Usable Capacities:  750GB
  • NAND Components: 128Gb 20nm Intel 3D XPoint
  • NAND Controller: Intel SSL3D 7-channel
  • Cache: none
  • Interface: U.2 PCIe 3.0 x4 NVMe
  • Form Factor: 2.5in 15mm
  • Dimensions: 101mm x 70mm x 15mm
  • Drive Weight: 140gmm

Firmware Version: 0325
