Hard drive enclosures are useful if you want to turn your hard drive into a more portable one.

Hard drive enclosures are useful if you want to turn your hard drive into a more portable one. For example if you move to a new PC, it might be cheaper to spend a little money on an enclosure and you get to keep all your old data without having to pay for a data transfer service.
This enclosure works on USB 2.0 (It uses 2 USB plugs - one for power and one for transfer), and is built from aluminium with oxidation treatment to prevent any decay.
For ATA (IDE) Drives only.
