Comparison of the two dominant file‑sharing protocols for mixed‑OS enterprise environments.
Updated October 22, 2026
SMB 3.2
Best when the environment is Windows‑dominant, needs built‑in encryption, and requires tight integration with Active Directory.
NFS 4.2
Best for Linux‑heavy data‑analytics, HPC, or container platforms where raw throughput and POSIX compliance matter most.
NFS 4.2 edges out SMB 3.2 on raw performance and POSIX fidelity, making it the protocol of choice for modern Linux‑centric data lakes, though Windows shops will still favour SMB for its turnkey security and management.
