Our picks for the best Steam Deck SSDs for gaming in 2024 come from our benchmarks and data collected from a large selection of modern M.2 2230 drives. When shopping for the best Steam Deck SSDs, you'll want to balance performance, capacity, and features against your budget. We've compiled a list of the best options below based on a variety of factors, but be sure to visit our in-depth SSD reviews for more details on each SSD, where we have additional testing under Windows along with plenty of analysis and benchmarking. The Steam Deck was the first portable gaming PC on the market to be widely successful. The waitlist was massive, but eventually users got their hands on the holy grail. One big limitation, however, was the size of the internal storage, with a good number of units being sold with only 64GB of capacity. It’s not difficult to add additional storage by way of a microSD card and/or external storage, but upgrading the internal SSD is a surer way of having reliable, fast storage. The SSDs below will also make a good choice for use with other gaming handhelds, like the Asus ROG Ally, MSI Claw, Lenovo Legion Go, and other devices that utilize M.2 2230 drives. Some users have experimented with modding and the use of larger M.2 2242 SSDs, cut-down SSDs, double-sided SSDs, and even ribbon cables to place M.2 2280 SSDs on the outside of the Steam Deck. However, the best and simplest option is to simply pick from the growing list of M.2 2230 SSDs that are fully compatible with the Steam Deck. You'll want a single-sided 2230 SSD as well, which allows for the EMI shielding to remain in place. This is critical so the drive does not interfere with the Steam Deck’s WiFi, and also a single-sided drive maintains the intended cooling configuration of the device.
