The Lexar NQ790 4TB is a PCIe Gen4 x4 NVMe M.2 2280 solid-state drive rated for up to 7,000 MB/s sequential read and 6,000 MB/s sequential write. Its 4TB capacity and 2,400 TBW endurance rating put it in the high-capacity tier where most rivals top out at 2TB or carry lower write-endurance figures. It is a DRAM-less design, so sustained heavy writes and random performance trail premium drives with onboard cache. It suits gamers, content hoarders and PS5 owners who want one large fast drive rather than a cache-heavy flagship.

Owners and reviewers treat the NQ790 as a solid value Gen4 drive that delivers near-advertised sequential speeds in short bursts. They note that sustained writes drop once the SLC cache fills, which is typical of DRAM-less designs. Most praise the capacity and endurance for the money.
