The Lexar Professional NM800 M.2 2280 NVMe SSD provides maximum SSD performance that puts you in the computing fast lane with speeds up to 7400MB/s read and 5800MB/s write, which is 12.7x the speed of SATA-based SSDs. It is also supported by the PCIe Gen4x4 NVMe 1.4 technology standard and backward compatible with PCIe 3.0, adding versatility to your professional workflow.

A Closer Look

Final Thoughts

The NM800 is small and is very easy to fit. The box contains the SSD and a screw to fit it into whatever device you want to use it in.

The NM800 can be used to either upgrade an existing PC with the correct slot, or if you wanted you could use it to upgrade your storage capability on your PS5, although if you are going down the PS5 route you should be aware that the NM800 doesn’t have a built in heatsink so you will need to buy one to add to it before you fit it into your PS5 (it only costs about £10 for a decent heatsink). For PC use you wont need a seperate heatsink and the NM800 handles it well, but Sony state you need one for SSDs and I wouldn’t take the risk of either the NM800, or your PS5 without adding one.

Fitting the NM800 was very easy – just slot it in and screw it down – that’s it!

Speed wise, the NM800 was excellent for both read and write – so no matter what you are using it for, whether its for games, music, videos, your Windows OS or anything else, you wont be disappointed.

They say good things come in small packages, and in the case of the Lexar NM800, they would be right.

The Lexar NM800 M.2 2280 PCIe Gen4x4 NVMe SSD is available now priced at around £99 for the 512GB version and £179 for the 1TB model.
