Alternatively called DAS, direct access storage, or direct access storage device, DASD describes any disk storage directly connected to the computer. A good example would be an internal or external disk drive that connects through an interface such as USB (universal serial bus) or FireWire.

Unlike a NAS (network access server), all storage devices connected to that computer become inaccessible if the computer is turned off.
