The Lexar EQ790 4TB sits at number 10 in this guide. It is a PCIe 4.0 NVMe M.2 2280 drive with a heatsink, priced at £469.99 and rated 4.6 out of 5 from 435 ratings. It is also the one drive here whose headline speeds do not change depending on where you read them: the bullets claim sequential read/write up to 7,000/5,000MB/s, and the spec table repeats 7,000 Megabytes Per Second for Read Speed, 7,000 Megabytes Per Second for Data Transfer Rate and 5,000 megabytes_per_second for Media Speed. There is no megabits-to-megabytes switch inside this listing, and no Gen5 figure printed for a Gen4 drive — it lists PCI Express 4.0 as its hardware connectivity and Sony PlayStation 5 among its compatible consoles.

The number that fails to fit its own label here is not a speed. The field marked 'Hard Disk Form Factor' reads 22 Millimetres, a thickness figure that matches the 2.2Th centimetres given in the item dimensions, while the separate Form Factor field for the same drive says M2. Everything on this page — the speeds, the price, the rating, the PS5 claim, the warranty — is taken from the Amazon listing as it stands; we have not benchmarked or handled this drive ourselves.

## Questions people ask

Yes. The spec table lists Sony PlayStation 5 under Compatible Video Game Console Models, and the bullets state that the drive is compatible with PlayStation 5.

**What read and write speeds does the Lexar EQ790 4TB claim?**
