The Lexar NM790 is fast thanks to its PCIe 4.0 connection: The affordable SSD all-rounder offers outstanding performance and is characterised by its exceptional energy savings and good thermal control. The only thing missing: hardware encryption and a 4 TB model.

Lexar relies entirely on Chinese components for the NM790: The Maxiotek MAP1602A SSD controller is joined by flash memory with 232 layers from YMTC. This puts the NM790 on a par with the Samsung 990 Pro in terms of read performance, with only 250 MB/s separating the two in terms of write performance...
