Chosen Solution
So I recently ordered a 256GB NVMe SSD Steam Deck to save money and I’m wondering if it Is possible to upgrade it to 512GB NVMe SSD. If so where can I get the 512GB NVMe SSD because I don’t see a part for it on iFixit I’m looking for the one officially made by valve if not will 3rd party SSDs work?
There are guides on that already, and yes it is possible. Just google it - or find it on iFixit as the guide is already present here. Obviously you will have to use a 3rd party SSD, again, easily found on google.
