storage device
A storage device, also known as a data storage device, is a device that stores digitalized information. For tagging purposes this term is limited to devices with a primary function, and practically only function is storing data. A computer, while being a storage device is capable of doing more than storing the data, and should not be tagged as a storage device.
Storage devices
For tagging purposes, storage devices that are primarily read only should use storage media instead. This includes any kind of optical disc, floppy disk, record, game cartridge, 8-track tape, and VHS tape.
