Be careful with external drives. We use them a lot at work and they fail on a regular basis, regardless of the company that manufactures them. If you're just using it to store things temporarily while you reformat another drive, it should be ok, but I wouldn't rely on it for a long period of time. Might make for a good backup drive, though, in case your primary drive fails, or for downloading/installing large amounts of data that you don't really care if you lose.
