WD Red Plus 12TB NAS HDD | 7200 RPM | CMR | 512MB | WD120EFGX

12TB NAS-Optimized Storage — High-capacity CMR hard drive purpose-built for 24/7 NAS operation in home and small business environments 7200 RPM | SATA 6Gb/s — Fast spindle speed and interface for quick data access and high-throughput file transfers Conventional Magnetic Recording (CMR) — Superior reliability and RAID compatibility compared to SMR drives for data-intensive NAS workloads 512MB Cache — Large buffer improves read/write performance during intensive multi-user NAS operations NASware Technology — WD’s NAS-optimized firmware for improved reliability, compatibility, and error recovery in multi-drive enclosures Advanced Vibration Protection — Compensates for vibration caused by adjacent drives in multi-bay NAS enclosures 24/7 Operation Rated — Engineered for continuous always-on NAS environments with enhanced thermal management 3.5" Form Factor — Direct-fit installation in most 1-bay to 8-bay NAS enclosures The WD Red Plus is Western Digital’s NAS-specific hard drive lineup designed for the unique demands of network-attached storage — 24/7 continuous operation, multi-drive vibration, and RAID workloads that desktop drives cannot reliably handle. The 12TB CMR configuration delivers the reliability and RAID compatibility that NAS users need, with NASware firmware fine-tuning error recovery, vibration tolerance, and compatibility with leading NAS platforms including Synology, QNAP, and others. At 7200 RPM with a 512MB cache, it provides strong throughput for media streaming, backup, and file sharing across home and small business networks.CMR (Conventional Magnetic Recording) technology ensures stable performance in RAID 0/1/5/6/10 configurations — unlike SMR drives which can struggle under the rewrite-intensive workloads typical in RAID rebuilds. Advanced vibration protection using integrated rotational vibration (RV) sensors maintains drive performance in multi-bay enclosures where mechanical vibration from neighboring drives can degrade performance. 24/7 rated with a 3-year limited warranty for dependable long-term NAS operation.Ideal For Home & Small Business NAS Systems — 12TB capacity for centralized file storage, media libraries, and backups RAID Arrays (0/1/5/6/10) — CMR technology for reliable RAID configurations without performance degradation Media Streaming & Plex Servers — High throughput for 4K media libraries and simultaneous multi-user access Backup & Data Protection — High-capacity, reliable storage for Time Machine, rsync, and backup solutions Multi-Bay NAS Enclosures — Vibration protection for stable operation in 4-bay to 8-bay configurations Specifications Model — WD Red Plus MPN — WD120EFGX SKU — CCWD120EFGX Capacity — 12TB Form Factor — 3.5" Interface — SATA III 6Gb/s Spindle Speed — 7200 RPM Cache — 512MB Recording Technology — CMR (Conventional Magnetic Recording) Workload Rating — 180TB/year 24/7 Rated — Yes Warranty — 3-year limited
