The Lexar NM790 1TB with heatsink is the third drive in this guide. It is a PCIe Gen4 M.2 2280 drive, and Lexar quotes up to 7,400 MB/s read and 6,500 MB/s write. It carries a 4.7 rating from 1,528 ratings and costs £189.99.

The number that stands out is the price, not the speed. The PS5 takes a Gen4 drive, so 7,400 MB/s is already more than the console can use — and the Lexar costs £10 more than the PCIe 5.0 Crucial P510 at £179.99 and £34 more than the Acer GM7 at £155.99, which quotes 7,200 MB/s. The same guide shows a heatsink adding £35 to the Lexar EQ790 (£179.99 with, £144.99 without) for identical quoted figures, which is a useful yardstick for how much of this £189.99 is the aluminium. The listing also contradicts itself on units: the bullet says 6,500 MB/s write, while the spec table gives Media Speed as '6500 megabits_per_second' — megabits, not megabytes, a factor of eight apart — and states the form factor as '0.23 Metres'. Everything on this page comes from the Amazon listing, not from testing of our own.
