Rank #3 in Best 1TB SSD for PS5: 10 Ranked, From £135.99 to £199.99
Lexar NM790 1TB with Heatsink
Price and rating as shown on Amazon when we collected them. Both change.
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.
How those 1,528 ratings break down
An average hides its own shape. This is the spread behind the 4.7 stars.
