If you often find yourself needing to temporarily connect bare hard drives (2.5″, 3.5″ or 5.25″) to your computer, a USB to SATA/IDE adapter is a nice investment.
A while ago, I bought the Sharkoon DriveLink. The nice thing about it is that it can run 2.5″ hard drives without the power brick. However, it would randomly disappear from the computer, interrupting any file transfers that may have been in progress. I returned it and got a replacement unit that showed the exact same behavior, so I returned it for a refund.
Instead, I bought the Scythe Kama Connect 2. So far, it’s been working like a charm.
