22TB WD WD221KFGX Red Pro NAS 7200RPM 512MB

For the needs of large companies
WD Red™ Pro hard drives are specifically designed for medium to large business customers and are available for NAS systems with up to 24 drive bays. Designed for high-intensity workloads in 24x7 environments, the WD Red™ Pro family is ideal for archiving and sharing content, as well as building RAID arrays in advanced operating systems such as ZFS and other file systems. These hard drives increase efficiency by enabling your employees to quickly share files and reliably back up folders in your NAS solution.

Exclusive NASware™ 3.0 technology
The exclusive and advanced NASware™ 3.0 firmware technology ensures seamless integration, robust data protection, and optimal performance for heavily used NAS systems. Integrated into every WD Red™ Pro hard drive, NASware 3.0 enhances your system“s storage performance with cutting-edge technologies and improved compatibility, integration, upgradeability, and reliability.

Designed for optimal NAS compatibility
WD Red™ Pro hard drives with NASware™ technology simplify hard drive selection. Our unique algorithm is optimized for NAS systems and ensures the right balance of performance and reliability in NAS and RAID environments. In short, WD Red™ Pro is the hard drive with the highest compatibility for NAS enclosures. The numbers prove it. WD Red™ Pro hard drives are the result of extensive compatibility testing and extensive integration of technologies from our NAS partners.

Shock protection for drive bays in large NAS systems
WD Red™ Pro hard drives feature a multi-axis shock sensor to detect even minor impacts and dynamic head height adjustment that automatically compensates for vibration during every read/write operation, protecting your data. The combination of these technologies provides even greater hard drive protection in large 24-bay NAS environments and increases drive reliability.

3D Active Balance Plus
Our advanced dual-level mass balancing technology significantly improves overall drive performance and reliability. Hard drives without proper mass balancing can cause excessive vibration and noise in a multi-drive system, reducing hard drive lifespan and degrading performance over time.

Protection through troubleshooting
Because WD Red™ Pro hard drives are specifically designed for RAID and NAS environments, they feature special error recovery mechanisms as part of NASware™ 3.0 technology, significantly reducing drive failures in RAID systems.

Comprehensive hard drive tests
A NAS environment with up to 24 drive bays places significant demands on a hard drive in terms of increased vibration and heat generation. Therefore, every WD Red™ Pro hard drive undergoes extensive temperature-fluctuating break-in testing to ensure even greater reliability during operation.

Longer warranty coverage
WD Red™ Pro hard drives are backed by a 5-year warranty for added peace of mind.

Desktop drives compared to WD Red™ Pro
Choose the right NAS-optimized hard drive with a wide range of features to protect your data and maintain peak performance. Consider the following when selecting a hard drive for your NAS system:
- Compatibility: Unlike desktop drives, these hard drives are specifically tested for compatibility with NAS systems to ensure optimal performance.
- Reliability: Continuous operation of a NAS or RAID is extremely demanding. Desktop hard drives are typically not designed and tested for these conditions – unlike the WD Red™ Pro.
- Error recovery mechanisms: WD Red™ Pro NAS hard drives are specifically designed with RAID error recovery protocols that help reduce failures in the NAS system.
- Noise and vibration protection: Desktop drives are designed for stand-alone operation and therefore typically offer little or no protection against the noise and vibration inherent in multi-drive systems. WD Red™ Pro hard drives are optimized for use in multi-bay NAS environments.
