I recently purchased a WD Passport portable hard drive and have been pleased with it so far. I was using it to run intermittent backups of my hard drive and the thought of having to plug one or the other (or both) into the wall wasn't something I was interested in.

You can stick a 7200 RPM notebook drive in a 2.5" enclosure with no problems. Heck, stick an SSD into a USB 3.0 2.5" enclosure and watch it fly. If you put a mechanical harddrive into a USB 3.0 enclosure, it won't even be able to keep up with the connection.
The key is to buy the harddrive and the enclosure separately to maximize your choices and $ value as a smart shopper.
