I ran into this sort of issue with the Steam Deck, too. Initially ordered a slower-but-still-recommended cheaper SD card. Figured I could deal with the slower write speeds as that should just mean slower downloads. I loved the Steam Deck from the onset, but was always confused why nobody mentioned how slow and unresponsive the main menus were... Yeah, hindsight is 20/20. Games still ran fine off of the slower card, but every part of the experience saw a dramatic improvement after I switched to a higher-spec SD card.
