Western Digital Red Pro 22TB, 3.5″ Internal Sata Hard Drive | WD221KFGX
Enterprise-class hard drives engineered to deliver high performance and reliability to commercial and enterprise NAS environments.
WD Red® Pro drives are engineered to handle high-intensity workloads in 24×7 multi-user commercial and enterprise NAS environments. WD Red Pro drives deliver the performance, scalability and dependability businesses require to store, share and collaborate on large amounts of data in multi-bay RAID-optimized NAS systems.
Optimized 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
WD Red Pro hard drives are designed to handle the rigorous demands of high-intensity 24×7 multi-user NAS environments and increase system durability.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.Protected against Excessive Vibration
WD Red Pro drives include Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances caused by increased vibration. By dispersing excess vibration across the drive chassis, turbulence is minimized, performance is maintained and drives are protected.Built to Absorb Shock
WD Red Pro hard drives include a multi-axis shock sensor to detect subtle shock events and automatically compensate with dynamic fly height technology to further protect the drives in NAS enclosures.Engineered with Industry-Leading Technology
WD Red Pro 22TB and 24TB hard drives feature Western Digital’s proprietary OptiNAND™ technology which leverages integrated iNAND embedded flash to perform key housekeeping functions, freeing up more capacity and improving the overall drive performance.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 5-year limited warranty and world-class support services for hassle free data storage.Desktop drives vs. WD Red® Pro
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 Pro 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 Pro hard drives are designed to perform under tough conditions encountered in high-intensity 24×7 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. -
