Product overview
Western Digital’s WD Red Plus 3TB (WD30EFZX) debuted on February 9, 2021, as part of the CMR‑based WD Red Plus NAS HDD family. It’s built for 1–8‑bay NAS with NASware firmware on a 3.5-inch SATA 6 Gb/s platform, 5400 RPM and a 128 MB cache.
Positioning: budget-tier storage—prioritizing reliable, cool, 24×7 operation over raw throughput. It exists to offer dependable mass capacity for home and small‑business arrays. Good for NAS mass storage and backups, home servers, or a budget desktop upgrade and cold game library. WD rates it for 180 TB/year workload with a 1M‑hour MTBF. Not discontinued as of July 2026. Notable: uses CMR (non‑SMR) recording, avoiding the write‑slowdown behavior SMR can show in NAS use.
