SATA 12,7mm Was perfect - including silicone dummies for gaps and unused space in the Caddy, so that a hard drive that can not be screwed, is fixed absolutely safe and a small screwdriver was also settled. The shutter switch screw was not a problem, on the panel, however, is a small pin, which had to be sunk in the Caddy. The hole provided was a bit small. Valued supplied screwdriver and hole minimal increases - already the problem was solved. Safe production process and may vary from piece to piece. 5/5 stars
