The Lexar NM790 4TB is a PCIe Gen4 x4 NVMe M.2 2280 SSD built on a DRAM-less design with a host memory buffer. It stands out for its high 4TB capacity, 7,400 MB/s sequential read and 6,500 MB/s sequential write speeds, and a 3,000 TBW endurance rating that is generous for its class. It suits gamers, content creators and PS5 owners who want fast bulk storage without paying flagship prices. Reviewers generally find it close to premium Gen4 drives in real-world use, though sustained writes slow once the SLC cache fills and it lacks a DRAM cache.

Owners rate it highly, praising real-world speed, cool operation and capacity for the money. Most criticism centers on sustained write drops and the DRAM-less architecture, which matters mainly for heavy write workloads.
