Lexar NM790 2TB PCIe Gen4x4 M.2 NVMe SSD Review

It’s been a while since we’ve had a Lexar product in for review, but there’s no doubt about it, Lexar is one of the biggest and most recognisable names in the world when it comes to storage. However, I mostly know them for their SD cards that I have in my phone, Switch and a whole host of other gadgets. Of course, today I’m taking a look at their latest PC hardware, the NM790, an M.2 2280 form factor PCIe Gen4x4 NVMe SSD. Promising speeds of up to 7400 MB/s, it’s certainly no slouch and should provide all the high-end performance you need from your PC, laptop or even the PlayStation 5.

The Lexar NM790 is ticking all the right boxes for an enthusiast-grade SSD, and the PCIe Gen 4 interface means that you’ll be getting twice the throughput of the previous PCIe Gen 3 SSDs, which is great for trimming down those gaming loading times, and especially beneficial to those dealing with larger file formats, which can seriously speed up photo and video editing tasks. There are a few capacities available, 512GB, 1TB and 2TB, but I have the 2TB model (LNM790X002T-RNNNG) in for review, which should strike a good balance between storage space and price.

As a child still in my 30's, I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
