I want to install an 2.5" SSD into a 3.5" desktop bay. I know I need an adapter to do this. Crucial has a drive that says in the description that it includes a 9.5MM adapter. Would this adapter be what I need for a desktop install or are they talking about something else? Here is a link to drive I am considering.
