The Steam Deck has the raw horsepower needed to play most of the 100+ GB games available, especially with the speed of the onboard SSD allowing for it to keep up with SSD-optimized games like Ratchet and Clank: Rift Apart. However, its limited space for these huge games and their multi-gigabyte shader caches is a real problem...a problem that a reviewer at Storage Review saw fit to solve with a 61 TB SSD.
Cool as the Steam Deck is, one of the biggest compromises of the little Linux handheld is the lack of storage. The best SSD you're getting with the Deck before user modding is the 512 GB NVMe drive that comes with the high-end model, which is admittedly not that much when you consider the 100-200 GB file sizes of demanding modern games.
