Review on 2 Pack Black SSD HDD Holder Adapter Bracket - Mounting 2.5 to 3.5 Hard Drive by Govindarajan Diepenbrock

Although they supply you with appropriately threaded screws, the outer holes (the part that usually connects to the mounting bracket for a 3.5" drive ) smaller threads used for floppy drives and removable media *not* the coarser threads used in cases and especially 3.5 inch hard drives. I can't think of a good reason for that. So if you expect to be able to mount this with dampening pads and longer screws for 3.5" drives, look elsewhere. Your 3.5" screws will not work with the drive carrier.
