About Windows Direct-Attached Storage (DAS)

Direct-attached storage, or DAS, refers to any storage system that is directly attached to one machine (such as a hard drive). Direct-attached storage cannot be shared with other servers or machines, making it less practical in large enterprises than networked storage such as network-attached storage (NAS) or storage area networks (SAN). This topic page features the latest news and expert advice for working with DAS for Windows operating systems, including details on the pros and cons of direct-attached storage and tips on troubleshooting DAS issues and problems.
