Tuned for NAS with NASware Western Digital's exclusive NASware technology fine tunes drive parameters to match NAS system workloads, which helps increase performance and reliability. Designed for Continuous Operation Since your NAS system is always on, a reliable drive is essential. WD Red Plus hard drives are designed for systems that operate 24/7, giving users the confidence of knowing they can reliably access their data. Tested for Dependable Compatibility Western Digital partners with a wide range of NAS system vendors for extensive testing to ensure compatibility with most NAS enclosures. Optimized for Lower TCO WD Red Plus drives are engineered to use less power (versus previous models) and run cooler, which reduces operating costs and helps reduce heat in thermally challenged NAS boxes. Powered for Strong Performance Despite using less power, the drives have plenty of bandwidth to handle the mixed performance demands of multi-drive NAS systems. Balanced for Increased Reliability Hard drives that are not properly balanced may cause excessive vibration and noise in multi-drive systems, which could reduce hard drive life span and degrade the performance over time. WD's enhanced dual-plane balance control technology significantly improves balance and increases overall drive performance and reliability. Limited 3-Year Warranty Western Digital stands behind their NAS storage solutions with the assurance of a limited 3-year limited warranty and world-class support services for hassle-free data storage. Reliability Desktop drives aren't typically designed for the demands of an always-on NAS environment. WD Red hard drives are designed to perform under tough conditions encountered in high-intensity 24/7 multi-user NAS environments. RAID Ready WD Red hard drives are engineered with RAID error recovery control to help reduce failures within multi-bay NAS systems, unlike most desktop drives that are configured for generic use. Noise and Vibration Protection Designed to operate solo, desktop drives typically offer little or no protection from the noise and vibration present in a multi-drive system. WD Red hard drives include Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances caused by increased vibration often found in multi-bay NAS systems.
