WD Red Pro NAS Hard Drive 22TB
 
Overview
WD Red Pro NAS HDD. For the Demands of Big Business.
Designed specifically with medium or large scale business customers in mind, 
WD Red Pro NAS HDDs 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 
3.0s 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 
dont 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 NAS HDDs 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 NAS HDDs 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.
Longer Warranty Coverage
WD Red Pro NAS hard drives comes with a 5-year limited warranty for an even 
greater peace of mind.
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: The always-on environment of a NAS or RAID is a hot one, and 
  desktop drives arent typically designed and tested under those conditions like 
  WD Red Pro drives are. 
- 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: 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 Pro drives are designed to thrive in multi-bay 
  NAS system environments.
