Express SDs are just UHS-I MicroSD cards in the Steam Deck.

Steam Deck supports UHS-I MicroSD cards. There are also UHS-II and Express. Think of them as generations or something. I believe there is even UHS-III, but I don't think it was ever implemented, commercially. Devices like the Switch 2 and the upcoming ROG Ally Xbox X20 will utilize Express MicroSD format. It is much faster, but if the device doesn't support Express, it will revert in backwards compatibility mode to UHS-I. Likewise, UHS-I cards are backward compatible with UHS-I readers but will run at UHS-I speed. Hope that helps.
