The WD Red series is engineered specifically for network-attached storage (NAS), built to run around the clock in multi-bay systems. Tuned with WD’s NASware firmware for compatibility and reliability, these CMR drives deliver dependable performance and data integrity for home and small-business NAS environments.
Choose the line that fits your workload. WD Red Plus (5400 RPM, CMR) is the value choice for NAS systems with up to 8 bays, ideal for backups, file sharing, and media libraries. WD Red Pro (7200 RPM, larger cache) is built for higher-intensity, performance-focused NAS and RAID setups, with capacities scaling all the way up to 26TB.
Every drive is backed by WD’s world-class support and warranty, and is designed for continuous, 24/7 operation.
