# DAS |  | Direct-attached storage (DAS) is digital storage directly attached to the computer accessing it, as opposed to storage accessed over a computer network. DAS consists of one or more storage units such as hard drives, solid-state drives, optical disc drives within an external enclosure. The term "DAS" is a retronym to contrast with storage area network (SAN) and network-attached storage (NAS). | |-|-| | | wikipedia:: [Direct-attached storage](https://en.wikipedia.org/wiki/Direct-attached_storage) | aka:: Direct Attached Storage
