WD Red Plus NAS Hard Drive

Powerful hard drives designed for performance, reliability and power efficiency in small to medium NAS environments.

WD Red® Plus drives are designed to handle workloads of power users and small to medium business NAS environments. WD Red Plus drives deliver the speed and capacity required to store, protect and share growing amounts of data in mid-sized RAID-optimized NAS systems with increased 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.

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.

Desktop drives vs. WD Red® Plus

It is important to choose a drive purpose-built for RAID-optimized NAS systems to ensure optimum performance and preserve your valuable data. Take the following into consideration when choosing a hard drive for your NAS:

  • Compatibility: Unlike desktop drives, WD Red Plus hard drives are specifically designed and tested for NAS and include NASware™ technology which fine tunes drive parameters to match NAS system workloads for optimum performance.
  • Reliability: Desktop drives aren’t typically designed for the demands of an always-on NAS environment. WD Red Plus hard drives are designed to perform under tough conditions encountered in high-intensity 24x7 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.
While the Red Plus 3.5" SATA III Internal NAS Hard Drive is a powerful storage solution, it is specifically engineered for optimal performance, reliability, and power efficiency in small to medium Network Attached Storage (NAS) environments. These drives are crafted to handle the demanding workloads of power users and small to medium businesses, delivering the speed and capacity necessary to store, protect, and share growing volumes of data in mid-sized RAID-optimized NAS systems. The Red Plus drives are enhanced with Western Digital's exclusive NASware technology, which fine-tunes drive parameters to match NAS system workloads.

This unique feature boosts performance and reliability, ensuring your data is always accessible in an always-on NAS system. Designed for continuous operation, these hard drives are built to withstand the rigors of 24/7 operation, providing users with the assurance of reliable data access. Western Digital collaborates with a broad spectrum of NAS system vendors to conduct extensive testing, ensuring the Red Plus drives are compatible with most NAS enclosures. The Red Plus drives are optimized for a lower Total Cost of Ownership (TCO), engineered to consume less power and run cooler than previous models.

This not only reduces operating costs but also mitigates heat in thermally challenged NAS boxes. Despite their power efficiency, these drives offer robust performance, with ample bandwidth to manage the mixed performance demands of multi-drive NAS systems. The enhanced dual-plane balance control technology significantly improves balance, boosting overall drive performance and reliability. Unlike generic desktop drives, the Red Plus drives are purpose-built for RAID-optimized NAS systems, ensuring optimal performance and data preservation. These drives are engineered with RAID error recovery control to minimize failures within multi-bay NAS systems. They also include Rotation Vibration (RV) sensors that proactively counteract disturbances caused by increased vibration often found in multi-bay NAS systems.

In summary, the Red Plus 3.5" SATA III Internal NAS Hard Drive is a reliable, high-performance, and power-efficient solution for your small to medium NAS environments.
