Red Plus Internal NAS HDD 3.5" - 4TB

Description

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

WD Red Plus internal HDDs are designed to handle workloads for 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.

Description

For the Demands of Big Business
Designed specifically with medium or large scale business customers in mind, WD Red™ Pro drives are available for up to 24-bay NAS systems. Engineered to handle high-intensity workloads1 in 24x7 environments, WD Red™ Pro is ideal for archiving and sharing, as well as RAID array rebuilding on extended operating systems such as ZFS or other file systems. These drives add value to your business by enabling your employees to quickly share their files and back-up folders reliably in your NAS solution.

Exclusive NASware™ 3.0 Technology
Our exclusive advanced firmware technology, NASware™ 3.0, enables seamless integration, robust data protection and optimal performance for NAS systems operating under heavy demand. Built into every WD Red™ Pro hard drive, NASware 3.0’s advanced technology improves storage performance by increasing compatibility, integration, upgradeability, and reliability.

Built for Optimum NAS Compatibility
WD Red™ Pro drives with NASware™ technology takes the guesswork out of selecting a drive. Optimized for NAS systems, our unique algorithm balances performance and reliability in NAS and RAID environments. Simply put, a WD Red™ Pro drive is one of the most compatible drives available for NAS enclosures. But don’t take our word for it. WD Red™ Pro drives are a reflection of extensive NAS partner technology engagement and compatibility-testing.

Larger NAS Bay Shock Protection
WD Red™ Pro drives are equipped with a multi-axis shock sensor that automatically detects subtle shock events and dynamic fly height technology which adjusts each read-write function to compensate and protect the data. This combination of technology further protects the drives in larger 24-bay NAS environments and helps increase hard drive reliability.

3D Active Balance Plus
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.

Error Recovery Prevention
Built specifically for RAID and NAS environments, WD Red™ Pro drives come equipped with error recovery controls as part of NASware™ 3.0 technology to help reduce drive fallout in RAID applications.

Extended Drive Testing
A NAS environment that has up to 24 bays is very demanding on a hard drive with added vibration and heat. This is why every WD Red™ Pro drive is shipped with extended thermal cycle burn-in testing to help ensure each drive is tested for extended reliable operation.
