One of those is that direct mounting of SSDs in most desktop computer cases is not possible due to lack of dedicated 2.5" drive bays. ECKDZMY Dual SSD Mounting Bracket is a perfect solution to this problem. It is an adapter specially designed to securely mount up to two 2.5" SSDs into existing standard 3.5" hard-drive bay. It fits any desktop computer case with at least one standard 3.5” hard-drive bay available. The installation is straight-forward, which makes for the hassle-free transition.
