That’s why we tracked down an
ADATA XPG Gammix S50 Lite, one of the slowest compatible PCIe Gen4 drives we could find at 3,900MB/s reads and 3,200MB/s writes, and stuck it into a PS5, along with another drive.
Yep, that’s a 3900MB/s drive all right.

We compared the S50 Lite against both the PS5’s internal SSD and a 5,000MB/s Sabrent Rocket 500GB in a battery of tests, including load times for games like early PS5 showcases
Ratchet and Clank: Rift Apart and
Spider-Man: Miles Morales. We also measured how long it takes to back up games to each kind of drive, throwing in a Seagate external HDD for comparison, since
Sony now allows you to archive PS5 games and play PS4 games from an traditional hard drive.
The verdict? Surprisingly, even the slowest compatible SSD we could find had near-identical load times to the one Sony includes in the box. Sometimes it’s a second slower, sometimes a second or two faster, but basically it’s a total wash. Hopping through dimensions in
Ratchet and Clank: Rift Apart, I saw no appreciable difference with the slowest SSD in gameplay, either. Stepping through pocket dimensions was instantaneous, and when there was a slight pause during a boss fight, I saw the same pause on the internal SSD as well.
