Rank #7 in Best 4TB SSD for PS5: 10 Ranked, and the Speed Numbers That Don't Add Up
Fikwot FX991 4TB PCIe Gen4 NVMe SSD
Price and rating as shown on Amazon when we collected them. Both change.
The Fikwot FX991 is a 4TB PCIe Gen4x4 M.2 2280 NVMe drive, seventh in this guide at £429.99. It is another entry where the headline number and the drive's own specification table do not agree with each other.
Fikwot's title and first bullet promise up to 7,300MB/s read and 6,300MB/s write. The spec table on the same listing gives a Read Speed of 7,000MB/s and a Media Speed of 6,200MB/s — 300MB/s lower on reads and 100MB/s lower on writes, inside one advert. The same table lists a Cache Memory Installed Size of 4TB, which is the drive's own capacity rather than a cache figure. The price, the 4.4 rating from 2,758 ratings and the 2,400TBW endurance figure all come from Fikwot's Amazon listing, and so does everything else on this page — we have not tested the drive ourselves.
How those 2,758 ratings break down
An average hides its own shape. This is the spread behind the 4.4 stars.
