Why each option
NAS (Network Attached Storage) is designed specifically for file-level access, allowing clients to access shared files over a network using protocols like SMB and NFS.
SAN (Storage Area Network) provides block-level access, presenting raw storage volumes (LUNs) to hosts rather than file system structures.
DAS (Direct Attached Storage) also operates at the block level and is physically connected to a single host, not accessible over a network as a file share.
SSD is a storage media technology (solid-state drive), not a storage access architecture - it can be used in NAS, SAN, or DAS systems and does not define an access method.
NAS provides file-level access by exposing shared directories to network clients via protocols such as SMB (Windows) and NFS (Unix/Linux). Clients interact with files and folders directly rather than raw blocks, making NAS the correct choice for file-level storage access.
