Lexar unveiled out the Professional NM800, a premium follow-up to its NM620 performance-segment SSD from Spring. The NM800 takes advantage of PCI-Express Gen 4 and NVMe 1.4 protocol, and comes in capacities of 512 GB and 1 TB. The 512 GB variant offers sequential transfer rates of up to 7000 MB/s reads with up to 3000 MB/s writes, and random-access throughput of 200k/500k (read/write) IOPS. The 1 TB variant, on the other hand, does up to 7400 MB/s sequential reads, up to 5800 MB/s sequential writes, and 400k/750k IOPS. The company didn't put out which combination of controller and NAND flash it is using, but we suspect that the drive is based on the Innogrit IG5236 "Rainer" controller, and Micron 3D TLC NAND flash. Endurance of the drives is rated at 250 TBW for the 512 GB variant, and 500 TBW for the 1 TB variant. The 512 GB variant is expected to be priced at 99€, and the 1 TB variant at 179€.
