Most of us have a portable hard drive that we use for transporting or backing up the data that we need the most. The only problem with external storage is that it is often bulky and ugly. You usually have power wires that you need to plug in and a housing that is large enough to fit a desktop 3.5" hard drive that is better suited for internal storage. In recent years many companies have begun to offer external storage solutions that use notebook hard drives and, in all honesty, that makes perfect sense. Notebook hard drives are designed from the start for abuse. Let's face it, we drop and toss around our notebooks way too often and the hard drive inside usually doesn't blow up on us.
