Powerful WD 3.5″ 4TB NAS Hard Drive designed for performance, reliability, and power efficiency in small to medium NAS environments!

The WD 3.5″ 4TB NAS Hard Drives are built for power users and small to medium-sized business NAS environments. These WD Red Plus drives offer the speed and capacity needed to store, safeguard, and share large amounts of data in mid-sized RAID-optimized NAS systems. Plus, they come with improved power efficiency.

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.

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 3.5″ 4TB NAS Hard 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 the hard drive life span and degrade the performance over time. Our enhanced dual-plane balance control technology significantly improves balance and increases overall drive performance and reliability.

Backed by World-Class Support and Warranty

As an industry-leading hard drive manufacturer, Western Digital stands behind its NAS storage solutions with the assurance of a 3-year limited warranty and world-class support services for hassle-free data storage.
