Rank #8 in Best 1TB SSD for PS5: 10 Ranked, From £135.99 to £199.99
SIX X7400 1TB Gen4 with Heatsink
Price and rating as shown on Amazon when we collected them. Both change.
The SIX X7400 is a 1TB PCIe 4.0 NVMe drive that sits at number 8 in this guide, and it is the one entry that undercuts the drives above it without quoting a speed the console cannot reach. It lists at £140.99, which is below the £155.99 Acer GM7, the £144.99 heatsink-less Lexar EQ790, and well below the two PCIe 5.0 drives at £179.99 and £199.99. Its headline figure is 7350 MB/s read over Gen4x4 — a bigger number than the £155.99 drive's 7,200 MB/s, on a generation the PS5 can actually use.
The listing then argues with itself. The same spec table that gives 7350 MB/s read speed also carries a Media Speed field reading 6700 megabytes per second, and a Hardware Connectivity field reading PCI Express x8 against a PCIE x 4 interface elsewhere on the page. The form factor is listed as '2280 Millimetres', which is 2.28 metres — the identical error that appears on the Crucial P510 in this round-up. The copy claims 'up to 40% fast performance' without saying 40% faster than what. Worth knowing before you buy: the first rating below says the bundled heatsink 'isn't really that good'. Everything on this page is taken from the Amazon listing and its customer ratings, not from any testing we have done.

Questions people ask
Will the SIX X7400 work in a PlayStation 5?
The listing names Sony PlayStation 5 under Compatible Video Game Console Models, and lists Gaming Console and PS 5 under Compatible Devices. It is a PCIe 4.0 drive, so it does not quote PCIe 5.0 speeds the console cannot use.
What read speed does the SIX X7400 actually quote?
The listing gives 7350 MB/s in its Read Speed and Data Transfer Rate fields, but its own Media Speed field says 6700 megabytes per second. Both figures come from the same Amazon page.
Does the SIX X7400 come with a heatsink?
The product name says 'with Heatsink', and the Box Contents field lists a screwdriver kit. One of the ratings says the supplied heatsink 'isn't really that good' and advises buying a proper one, while two others describe fitting it using the included thermal pad.
What form factor is the SIX X7400?
The listing says M2 and 2280. Its Hard Disk Form Factor field reads '2280 Millimetres', which would be 2.28 metres — the same error that appears on the Crucial P510 in this guide.
What warranty does the SIX X7400 carry?
The listing states a 5 years limited warranty, and its EU Spare Part Availability Duration field also reads 5 Years.
How does the SIX X7400 price compare with the rest of the guide?
At £140.99 it is cheaper than the £155.99 Acer GM7 and the £144.99 Lexar EQ790 without a heatsink, while quoting 7350 MB/s read against the Acer's 7,200 MB/s.
