Lexar NM790 (PCIe 4.0 NVMe/7,400 MB/s Read/Value Flagship-Speed Drive) Review
Lexar NM790 PCIe 4.0 NVMe SSD, added as a replacement after the originally planned Kingston FURY Renegade G5 turned out to already be in the catalog; a value flagship-speed drive.
This is the drive that made a lot of enthusiasts reconsider paying flagship prices at all — it hits essentially the same peak numbers as far pricier PCIe 4.0 flagships despite skipping the DRAM cache, leaning on Host Memory Buffer instead. Sustained write consistency isn't quite at Samsung 990 PRO levels once the SLC cache empties, but for the price it's one of the best speed-per-dollar NVMe drives available.
Comparison to Alternatives
Against the Kingston KC3000 already in this catalog, the NM790 matches peak sequential speeds closely while typically costing less, though the KC3000's DRAM cache gives it an edge in sustained write consistency. Compared with the Crucial T500, the NM790 undercuts significantly on price while accepting a modest sustained-performance tradeoff from its DRAM-less design.
