I saw a Youtube channel recently test most available PCie Gen4 drives for the PS5. Apparently the best drive for the PS5 is the Seagate Firecuda 530 however its not cheap. As above the SN850 and 980 Pro are also great drives (Although the 980 pro isnt as good as the Seagate drive and generally more expensive). For the more budget conscious, the Crucial P5 Plus is a great drive its £107 at the mo, bung on a £10 heatsink and you are good to go.
