The WD Black SN770M 2TB is a great choice for expansion cards for smaller computing devices such as the Steam Deck. The SN770M uses a small M.2 2230 form factor, enabling it to fit in the tiniest chassis. So if you're looking to expand the storage of your gaming handheld or laptop, then the WD Black SN770M would be an excellent choice.
