Have you managed to get hold of a Steam Deck and need a way to pack it full of all your games? There are two ways to expand the storage capacity of this portable console and change the way you play games. One is through the use of microSD cards and the other is the replacement of the internal SSD. The easiest method is adding a microSD card, the same form of storage that can be used to expand the capacity of a tablet or smartphone. The microSD card can be any size, but it should support the UHS-I speed standard, which most microSD cards support these days.
