Ideal for record 1 T0. For the 2 T0, I do not know but they must be of the same size if they are "My passport".
Hard plastic shell with rubber inside to absorb shocks. Hermetic closure with rigid does not let dust, keeps the drive perfectly inside. The disc is wedged in his cabin.
The hard drive can be used without removing it from the shell because there is a small hatch at the bottom of the hull to connect the necessary USB3 socket. This blocks the dust trap passage also. It is true that one does not know it store the cable but such storage would thereby expand the case of at least 4/5 cm to maintain the maximum protection of the disk and would have made an object bulkier.
Of course, this is a high quality hull so it is more expensive than a small suitcase in which the hard drive is never really maintained. Usual quality of Western Digital.
