Desktop Drives vs. WD Red™ Pro
To optimize your NAS, choose a drive purpose-built for NAS systems, offering features to preserve data and maintain optimum performance. Consider the following:
- Compatibility: Unlike desktop drives, these drives are specifically tested for compatibility with NAS systems for optimum performance.
- Reliability: NAS and RAID environments are demanding (always-on, higher heat). WD Red™ Pro drives are designed and tested for these conditions, unlike typical desktop drives.
- Error Recovery Controls: WD Red Pro NAS hard drives feature RAID error recovery control to help reduce drive failures in RAID applications.
- Noise and Vibration Protection: Desktop drives offer little protection against noise and vibration in multi-drive systems. WD Red Pro drives are designed to thrive in multi-bay NAS environments.
For the Demands of Big Business
Designed for medium to large scale business customers, WD Red™ Pro drives are suitable for up to 24-bay NAS systems. They are engineered to handle high-intensity workloads in 24x7 environments, making them ideal for archiving, sharing, and RAID array rebuilding on extended operating systems like ZFS. These drives enable employees to quickly share files and back up folders reliably within a NAS solution.
Exclusive NASware™ 3.0 Technology
This advanced firmware technology enables seamless integration, robust data protection, and optimal performance for NAS systems under heavy demand. Built into every WD Red Pro hard drive, NASware 3.0's technology enhances storage performance by improving compatibility, integration, upgradeability, and reliability.
Built for Optimum NAS Compatibility
WD Red Pro drives with NASware technology simplify drive selection. Optimized for NAS systems, their unique algorithm balances performance and reliability in NAS and RAID environments, ensuring high compatibility with NAS enclosures. This is a result of extensive NAS partner technology engagement and compatibility testing.
Larger NAS Bay Shock Protection
WD Red Pro drives feature a multi-axis shock sensor that detects subtle shock events. Dynamic fly height technology adjusts read-write functions to compensate and protect data. This combination enhances drive reliability in larger 24-bay NAS environments.
3D Active Balance Plus
This enhanced dual-plane balance control technology significantly improves overall drive performance and reliability. Improperly balanced hard drives can cause excessive vibration and noise in multi-drive systems, reducing drive lifespan and degrading performance over time.
Error Recovery Prevention
Built for RAID and NAS environments, WD Red Pro drives include error recovery controls as part of NASware 3.0 technology to help reduce drive fallout in RAID applications.
Extended Drive Testing
NAS environments with up to 24 bays place significant demands on hard drives, including added vibration and heat. Every WD Red Pro drive undergoes extended thermal cycle burn-in testing to ensure reliable operation.
Longer Warranty Coverage
WD Red Pro drives come with a 5-year limited warranty for enhanced peace of mind.

Specifications subject to change without notice. ¹ Not all products may be available in all regions of the world. ² As used for storage capacity, one gigabyte (GB) = one billion bytes and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. ³ WD hard drive products manufactured and sold worldwide after June 8, 2011, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the RoHS Directive 2011/65/EU. ⁴ Up to stated speed. As used for transfer rate, 1 MB/s = 1 million bytes per second. Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and other factors. ⁵ As used for cache, one megabyte (MB) = 1,048,576 bytes. ⁶ Controlled unload at ambient condition. ⁷ MTBF specifications are based upon internal testing using a 40°C base casting temperature. MTBF is based on a sample population and is estimated by statistical measurements and acceleration algorithms. MTBF does not predict an individual drive's reliability and does not constitute a warranty. ⁸ Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred x (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations. ⁹ See http://support.wd.com/warranty for regionally specific warranty details. ¹⁰ Power measurements at room-ambient temperature.
