I bet when you were watching Steam Deck‘s first media presentation, you probably weren’t thinking: “Hmm, yes. Looks good, but what storage medium are these games running from?” That’s the sort of question that arrives later. But it’s worth asking, because even the biggest and best of Valve’s new portable PCs only has 512GB of drive space. I eat that for breakfast. As it happens, a lot of the games we’ve seen running already were stored on a microSD card.
