Knowing how to upgrade your Steam Deck SSD is important if you want to expand the handheld’s internal storage. Valve’s device has up to 512GB of SSD storage but that might not be enough, especially if you play games with file sizes well over 100GB. Thankfully, installing a new SSD with more storage is relatively easy.
You’ll need a Steam Deck, a computer, one USB-C flash drive with at least 10GB of space, a small Phillips screwdriver (size 0) and a plastic seam splitter or even a credit card. You’ll also need a 2230 NVMe SSD, which is a smaller version of a normal NVMe. I installed the Corsair MP600 Mini SSD, but there are several others to choose from.
