Corsair MP600 PRO LPX 4TB PS5 SSD

The Corsair MP600 PRO LPX 4TB is the runner-up in this guide, at £415.01 with 4.8 out of 5 from 10,543 ratings. It is a PCIe Gen4 x4 NVMe drive, which is the generation the PS5's M.2 slot actually runs — the listing says it "exceeds all Sony PS5 M.2 performance requirements" and ticks Sony PlayStation 5 under Compatible Video Game Console Models. Its headline read figure also survives the check that trips up other drives here: the bullets claim up to 7,100MB/sec sequential read, and the spec table's Read Speed field says 7100 Megabytes Per Second. Same number, same unit.

The write figure appears twice as well — up to 6,800MB/sec in the bullets, and 6.800 MB/s under Media Speed, with a comma standing in for the decimal point. Where the listing does slip is the field labelled Data Transfer Rate, which reads 7100 Megabits Per Second. Megabits, not megabytes: an eight-fold gap with the Read Speed field on the same page. Two smaller oddities sit beside it — the drive is listed under Product Features as "Portable" and under Hard Disk Form Factor as "2.5 Centimetres", neither of which describes an M.2 stick. Everything on this page comes from the Amazon listing, not from any testing by us.
