Storage in this term is categorized into 3:

  • Network Attached Storage (NAS)

  • Direct Attached Storage (DAS)

  • Storage Area Network (SAN)

Network Attached Storage (NAS) is file-level computer data storage connected to a computer network providing data access to a group of clients’ computers. NAS operates as a file server for storing, serving and sharing files.

Direct Attached Storage (DAS) refers to a digital storage system directly attached to a Server or Workstation without a storage network in between.

Storage Area Network (SAN) is a dedicated high-speed special-purpose network that interconnects different kinds of data storage devices with associated data servers on behalf of a larger network of users. SANs are primarily used to make storage devices accessible to servers so that the devices appear like locally attached devices to the operating system.
