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 take 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 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's life span, and degrade 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.

Desktop drives vs. WD Red™ Pro

Do right by your NAS and choose the drive purpose-built for NAS with an array of features to help preserve your data and maintain optimum performance. Take the following into consideration when choosing a hard drive for your NAS:

Compatibility: Unlike desktop drives, these drives are specifically tested for compatibility with NAS systems for optimum performance.

Reliability: A NAS or RAID's always-on environment is hot, and desktop drives aren’t typically designed and tested under those conditions like WD Red™ Pro drives.

Error Recovery Controls: WD Red™ Pro NAS hard drives are specifically designed with RAID error recovery control to help reduce failures within the NAS system.

Noise and Vibration Protection: Desktop drives, designed to operate solo, typically offer little or no protection from the noise and vibration present in a multi-drive system. WD Red™ Pro drives, on the other hand, are designed to thrive in multi-bay NAS system environments.
