Lexar Professional NM800 Pro Heatsink 2TB SSD Review

Rating: 8.0.

The latest model to join Lexar's stable of SSD drives is the Professional NM800 Pro, a PCIe Gen4 drive that uses an 8-channel controller and 176-layer 3D TLC NAND. In for review is the 2TB model, retailing for around £230.

The Lexar Professional NM800 Pro is available (at the time of writing) in three capacities; 512GB, 1TB and a 2TB flagship and two versions, plain and one with a heatsink installed (the drive we are reviewing). At the heart of the drive is an InnoGrit IG5236 controller looking after 176-layer 3D TLC NAND.

Officially the 2TB NM800 Pro is rated as up to 7,500MB/s for Sequential reads and up to 6,500MB/s for writes. The 1TB drive gets the same read maximum but the writes drop to 6,300MB/s while the 512GB model is rated as up to 7,450MB/s and up to 3,500MB/s for read and writes respectively. There are no details about the 4K random performance on the specification sheet for the drive.

Lexar quote an endurance rating for the 2TB Professional NM800 Pro Heatsink as 2,000 TBW (Terabytes Written). The 1TB drive is rated at 1000TBW and the 512GB model, 500TBW. Lexar backs the drive range with a 5-year warranty.
