Although most smartphone manufacturers have ditched the microSD card slot as an expandable storage solution, that isn't true for every type of handheld device. Great gaming handhelds are becoming increasingly popular in 2023, with devices like the Nintendo Switch, Steam Deck, and ROG Ally offering great experiences in a mobile form factor. Where these devices can suffer is in terms of storage space, and although you can swap out the SSDs on some models, popping in a microSD card is a lot easier. It just so happens that you can grab a massive 512GB microSDXC card for just $32 during Amazon's Prime Big Deal Days, which is less than the cost of the average video game.
