目前，Steam Deck 只支持最小尺寸的 M.2 硬盘，即 2230 系列。虽然这台机器也可以用 microSD 卡扩展存储空间，但载入速度比 M.2 硬盘要慢。所以一位玩家找到办法改装了 Steam Deck，让其可以支持更大尺寸的 M.2 硬盘。不过 Steam Deck 开发工程师 Lawrence Yang 对此表示，不建议玩家进行这种改装。虽然这种方式看起来很有效，但会大大缩短 Steam Deck 的寿命。这个改装可以让 2242 系列尺寸的 M.2 硬盘装入 Steam Deck。玩家需要移开一个散热垫，并使用一个 30 to 42 的延伸支架，这样长尺寸的硬盘螺丝才可以在主板上固定。这些改变没有干扰到设备的其他部分，SteamOS 也可以成功安装到新硬盘上。（装上延伸支架）（装上新硬盘）虽然
At present, steam deck only supports the smallest m.2 hard disk, i.e. 2230 series. Although this machine can also use microSD card to expand the storage space, the loading speed is slower than the m.2 hard disk. So a player found a way to modify the steam deck to support a larger m.2 hard disk. However, Lawrence Yang, a steam deck development engineer, said that players are not recommended to make such modifications. Although this method seems to be effective, it will greatly shorten the life of steam deck. This modification allows m.2 hard disk of 2242 series size to be loaded into steam deck. Players need to remove a cooling pad and use a 30 to 42 extension bracket, so that the long hard disk screws can be fixed on the motherboard. These changes do not interfere with other parts of the device, and steamos can be successfully installed on the new hard disk. (install the extension bracket) (install the new hard disk) although
