HDD to USB Adapter thing?

[johnrain5440]

Thought I'd ask before buying, but anyways what's the adapter called for the HDD to USB? I have this hard drive and I'd like to use it as like an external instead of internal.

External USB enclosure. The 3.5" HDDs need external power. The 2.5" HDDs can usually run off of USB power, though they'll also work in a 3.5" enclosure (with external power).

There are also SATA-to-USB adapters, which let you drop in a HDD (doesn't fully enclose them). These are great for techies who frequently need to check what's on a HDD without fully installing it in a computer or enclosure. But I wouldn't recommend for carrying a drive around.
