WD Red Plus Internal NAS HDD 3.5" (2Tb, 4Tb, 6Tb, 8Tb, 10Tb and 12Tb)

The WD Red Plus is engineered for always-on NAS systems, small business file servers, and multi-drive storage environments. It’s ideal for users who need reliable, continuous access to data in RAID-optimized setups—whether for shared media libraries, active backups, or surveillance recordings.

The WD Red Plus drive supports high-workload, 24×7 operation with a rated 180 TB/year workload rate and 1 million-hour MTBF, making it designed for multi-drive NAS systems. It features ∼5400 RPM rotational speed, 64 MB cache (in the 2 TB model), CMR (Conventional Magnetic Recording) technology for consistent performance, and the proprietary NASware™ firmware for enhanced compatibility and stability in NAS enclosures. It’s optimized to run cooler, more quietly, and more efficiently in RAID-based systems with up to 8 bays.
