Features

  • 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 24x7, 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. 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 their NAS storage solutions with the assurance of a 3-year limited warranty and world-class support services for hassle free data storage.

    NAS drives

    The drives were recommended for use in a new NAS drive system for online backup and file sharing. It was hard to find them online but BestBuy came through. So far, the system is working fine and the drives are performing as they should. Thanks!

    Great

    As expected. No complaints. Plug and play. Couldn’t find purple for video recording so opted for red.
