When I bought my Steam Deck over a year ago, I purchased the basic model with a very unassuming 64GB eMMC module for primary storage. I knew this wouldn't be enough on its own for holding the games I like to play, so I've gotten by with having my Steam library installed on an SD card. This has worked surprisingly well, despite the lower performance of the SD card when compared to something like an NVMe. Load times, etc actually weren't all that bad! Alas, all good things must come to an end.....
