Alternatively referred to as digital storage, storage, storage media, or storage medium, a storage device is any hardware capable of holding information either temporarily or permanently.
There are two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, like a hard drive. Secondary storage can be removable, internal, or external storage. The picture shows an example of a Drobo, an external secondary storage device.
Without a storage device, your computer would not be able to save any settings or information and would be considered a dumb terminal.
