You may receive an HD is well protected therein. The need for the overall height of 4 cm a not obvious, however. I bought it for a WD My Passport Ultra HD - and will not use them with safety. Far too thick. Sure, it's my own fault if I have not been made aware that such a height is absurd despite cable integration. You learn from mistakes. Now have the "ABZ-S Case for External HD Portable EVA Hard Shell Material" bought. HD fits with cable into perfect and does not take up more space than necessary. (An extra-small hard disk to buy to save space and then create a giant transport cage around it is indeed questionable). I have learned.
