Technology is provided for a storage card adapter. The storage card adapter is used for housing storage cards (e.g., M.2 storage cards), and the storage card adapter can then be inserted into a drive bay. The storage card adapter includes an adapter frame and an adapter cover. The adapter frame includes a pair of guide posts having a ledge upon which one end of a storage card rests when the storage cards are installed in storage card connectors on a printed circuit board installed in the storage card adapter. The adapter cover includes a pair of clamping posts that are aligned to engage with the guide posts when the adapter cover is fully mated with the adapter frame. In this manner, the end of the storage card becomes clamped between the guide post and the clamping post to thereby secure the storage card within the storage card adapter.
