Even the UHS-I-limitation of the Steam Deck is good enough for 99.9% of the games (and much faster than the HDDs in PS4 Pro/Xbox One X). If Nintendo uses a UHS-II microSD card reader, up to 300 MB/s reading speed is possible. |
I inferred this from the fast load times of the Zelda demo at Gamescom.

In the demo the load time was instantaneous, but usually it is 30 seconds.
Switch cartridges load at 60-95 MB/s.
