I got a 2.5" caddy from ayagroup and did not screw in any of the three screws that came with the SuperDrive (and only have two of them on hand) because it seemed tight in place. There's also space between the hard drive and the open area which leads me to believe maybe the SSD is rattling when mistreated:
what do you think? should i screw in the superdrive screws?
