DAS (Direct Attached Storage) connects directly to a server, offering high performance but limited scalability and sharing.
SAN (Storage Area Network) uses a high-speed network to share storage among multiple servers, providing high performance and scalability.
NAS (Network Attached Storage) is connected to a network to act as a file server, supporting simultaneous access by multiple servers and ideal for file sharing.
