NAS (Network-Attached Storage) connects to a network to provide shared access to files. It is used for storing and accessing data over a network, making it ideal for small businesses or home use.
DAS (Direct-Attached Storage) is directly connected to a computer or server without a network. It’s typically used for individual users or specific systems that require dedicated storage.
SAN (Storage Area Network) is a high-speed network of storage devices that provides block-level access to data. SANs are ideal for large enterprises needing high performance, redundancy, and scalability.
