An external hard drive sits outside the main computer tower in its own enclosure. The enclosure is slightly larger than the hard drive itself, and sometimes contains a cooling fan. This portable encasement allows the user to store information on a hard drive that is not inside the computer, but rests on a tabletop or surface nearby the computer. The external hard drive is connected to the computer via a high-speed interface cable. The interface cable allows the external hard drive to communicate with the computer so that data may be passed back and forth. The most common types of interfaces are USB and Firewire.

A portable or external hard drive is quite a useful piece of equipment. It allows the user to back up or store important information separate from the main internal hard drive, which could become compromised by online or offline activities. Sensitive documents, large music files, DVD images, movies, disk images, and even a backup of the contents of your main internal hard drive, can all be kept securely and safely on an external hard drive. When you are online, you can even leave the external drive turned off.

Another advantage of an external hard drive is that it is portable and operates on a plug-and-play basis. Any computer with USB or Firewire capability will recognize the external hard drive as a storage device, and assign it a letter to designate it. The drive can then be accessed like a normal internal hard drive. It's a snap to transfer huge files back and forth from work to home, to a friend's house, or between your desktop and laptop. Just plug in the interface cable to quickly reconstruct a working environment, making your favorite programs virtually portable
