Which of the following typically provides a FASTER access speed in a network storage implementation?

NFS is a file-level network protocol that adds significant overhead from TCP/IP encapsulation and the network stack, making it the slowest of the options listed.

SAN provides block-level storage over a dedicated network (Fibre Channel or iSCSI) and is faster than NFS, but still incurs network fabric latency that DAS avoids.

With DAS, the storage device connects directly to the server via interfaces such as SAS or SATA, meaning I/O requests do not traverse any network fabric. This eliminates the latency introduced by network switches, HBAs, and protocol encapsulation. As a result, DAS consistently delivers lower latency and higher throughput compared to any network-based storage option.

SATA is a physical drive interface and bus technology, not a storage implementation or access method; it describes how a drive connects internally, not a network storage solution.
