So I did buy a 512GB microsd card for my Steam Deck.

Based on my research, the most important spec sounds like the "A2" signifier when it comes to using it to install games and load apps and such:

Bought a 512 GB SanDisk Extreme (A2) a few months ago for the Steam Deck (it was on sale, almost as cheap as A1 cards).

But I'll also use a 400 GB SanDisk Ultra (A1) laying around. On this card there are 140 small deck-compatible games (0 - 7 GB each), where A1 IOPS will be more than enough. These games were made for HDDs with a few hundred IOPS.

No big differences on read speeds between A2 and A1 cards:

For comparison: two of my HDDs with much much worse random read speeds:

So don't worry about using A1-cards in the Steam Deck. It will be fine for most games.
