The Asus ROG Ally Laptop launches with speed, and I’m not just talking about its speedy processor that sets it apart from the Steam Deck and other competitors. ROG Ally’s UHS-II microSD card interface enables faster read and write speeds than UHS-I, the base spec found in the Steam Deck, Nintendo Switch, and several other devices. In other words, you’re likely to see much faster download speeds.
According LexarUHS-II triples the maximum transfer speed of UHS-I, reaching 312 MB/s instead of 104 MB/s. However, compared to the proliferation of slower microSD cards, there are very a few UHS-II microSD cards out there.

However, there is good news that UHS-II microSD cards are backwards compatible with UHS-I gadgets, such as the Steam Deck, although you will see slower transfer speeds than what you paid for. the big prize.
We’ll keep this list updated as new microSD card models are released.
