Our take on the Lexar NM790 M.2 2280 PCIe Gen 4x4 NVMe Internal Solid-State Drive, 1 TB

The Lexar NM790 is a PCIe Gen 4x4 M.2 2280 NVMe SSD built on a DRAM-less design that leans on HMB 3.0 and a dynamic SLC cache. Lexar rates the 1 TB model at up to 7,400 MB/s read and 6,500 MB/s write, which puts it in the same class as big-name Gen 4 drives for everyday use. It fits desktops, laptops and the PlayStation 5, and its low power draw and slim single-sided layout suit laptops and handhelds. Reviewers treat it as a strong value pick, though sustained writes and heavy random workloads fall short of premium drives with DRAM.

Questions and answers

Does the Lexar NM790 work in a PlayStation 5?
Yes. It is a PCIe Gen 4x4 M.2 2280 drive, which meets Sony's requirements. The PS5 needs a heatsink, and this drive does not include one, so buy a compatible heatsink or a version that has one.
Is the NM790 fast enough for gaming and video editing?
For gaming and everyday editing it is quick, with reads up to 7,400 MB/s. Very large file transfers slow down once the SLC cache fills, so constant heavy writes suit a DRAM-equipped drive better.
Does it come with a heatsink?
No. The standard NM790 is a bare single-sided M.2 2280 drive. That keeps it thin enough for laptops, but desktop and PS5 users should add a heatsink.
Will it fit my laptop?
It fits any laptop with an M.2 2280 PCIe Gen 4 or Gen 3 slot. The single-sided layout helps in thin models. Check your laptop's slot length and keying before buying.
Is it worth choosing over a DRAM drive?
For games, media and general use, most owners find the difference small. If you regularly move huge files or run heavy random workloads, a DRAM drive holds speed better.
What is in the box?
The drive itself, with no heatsink, screws or cloning software included. You supply the mounting screw if your board does not have one.
