Internal hard disk drives (HDDs) are normally used as the primary data storage within computing devices or RAID storage systems. These devices can and do fail, it’s a matter of when they will fail, rather than if they will fail.
External hard disk drives (HDDs) are intended to be used as secondary storage or backup hard drives. However, many decide to use them as extended storage or portable storage rather than as a reliable backup device. Portable and easy to use external hard disk drives typically use one or more standard 2.5″ or 3.5″ internal hard drives in a portable enclosure that connects to a computer’s USB or other data port.
