Housed inside the computer case making it well protected from the outside, however internet threats, virus or spyware will still put your hard drive at risk. Losing important information, documents or files can be frustrating, this is where an external hard drive may come in handy.
An external hard drive (hdd) is a hard drive situated outside the computer case in its own housing or enclosure. A bit bigger than a hard drive; the external hdd uses high-speed interfaces such as USB, firewire or eSATA instead of the older IDE connections. Some external hard drives have one or more cooling fans to keep the hard drive cool and prevent overheating.
