Because WD Network drives are specifically engineered for NAS systems with up to 5 drive bays, it's easy to seamlessly integrate these drives into your NAS system. They are designed and extensively tested for compatibility in the unique 24x7 operating environment and demanding system requirements of home and small business NAS. The secret is in the technology. Advanced firmware technology built into every WD Network hard drive, enables seamless integration, robust data protection and optimal performance for systems operating in NAS and RAID environments. Innovative technology reduces power consumption and lowers the operating temperature, resulting in a more reliable and affordable solution for always on 24x7 NAS environments. Your NAS system is always on. A highly reliable drive is essential. With a 35% MTBF improvement over standard desktop drives, the WD Network drives are designed and manufactured to be a more reliable and robust solution for your NAS system. Our enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time.
