To start off, the standard Steam Deck has a storage space of 64 GB. That maybe sounded like a lot a decade ago, but it is barely enough to contain two games. If the selling point is having basically a portable computer, it sucks that I have to keep installing and uninstalling in order to play other games. For one thing, the download speeds are not as fast, another thing, it’s just a hassle that forces you to constantly wait around. Luckily, it’s possible to augment the Steam Deck’s storage with a microSD. External hard drives are also a good option to increase space.
