Which storage type allows file-level access through a network?

Network Attached Storage (NAS) is specifically designed to provide file-level access to stored data over a network. This system acts as a dedicated file server that enables multiple users and devices to retrieve and store files using standard network protocols, such as NFS (Network File System) or SMB (Server Message Block). Because NAS operates at the file level, it simplifies data sharing and management among various clients in a networked environment.

In contrast, Direct Attached Storage (DAS) connects directly to a single computer or server, making it not suitable for file-level access by multiple users over a network. Storage Area Network (SAN) provides block-level storage, which is optimized for high-performance applications, but it does not provide direct file-level access like NAS. Object storage enables data to be stored as objects and accessed via APIs, but it does not operate through traditional file access methods used in networking. Therefore, NAS is uniquely positioned to offer the file-level access needed through a network.
