An external hard drive is the same kind of device used to store your digital information on a unit separate from your computer. For this reason, it is often used to backup data in the event of a hard drive crash or other malfunction. Like most people, if you keep your family photos in your computer, and if you don't have an external hard drive, you run the risk of losing them forever if your computer breaks down. But if you store them on the external devise, your pictures will be preserved.

In addition to backing up your data, an external hard drive can also be used to supplement the storage space you already have on your computer. More people are keeping more information on their computers, like movies and music. Files like these can quickly fill up all the available storage space on on your computer, which can have a negative effect on your computer's speed and your hard drive's stability.

External hard drives are very easy to use. Usually, all you need to do is connect it to your computer via a common USB port. Sometimes, if you have the available interface on the computer and depending on the model of your external hard drive, you may also use a Firewire cable for greater transfer speeds. It is also possible to interface with your external hard drive wirelessly for greater convenience.

The most common variety of external hard drives for computers are disk drives, which store information on a magnetic disc and is read by a small stylus.
