WD Red Pro 3.5" 14TB, 7200 RPM, 512MB, 550 WRL, SATA III Hard Drive for NAS

The Western Digital Red Pro WD142KFGX is a 14TB internal hard drive with a 3.5-inch form factor, engineered for multi-bay NAS and server environments. It is specifically intended for mid-sized to large NAS deployments that handle intensive read and write operations. The drive integrates NASware 3.0 technology to improve compatibility, data protection, and overall performance within NAS systems. This firmware helps manage the drive's behavior in multi-drive configurations, addressing common issues like error recovery and power usage.

This model operates at a 7200 RPM spindle speed and utilizes a 512 MB cache alongside a SATA 6Gb/s interface to achieve consistent throughput. It is built for continuous 24/7 operation and is equipped with rotational vibration (RV) sensors. These sensors detect and counteract vibration in real-time, which maintains performance and reliability in chassis with multiple drives. The drive's design focuses on data integrity and accessibility for collaborative workloads and large-scale data archival.
