WD hard disk 22TB SATA3, 6Gb/s, 7200, 512MB RED PRO

Enterprise-class hard drives designed to deliver high performance and reliability in commercial and enterprise NAS environments.

WD Red® Pro drives are designed to handle high-intensity workloads in multi-user commercial and enterprise NAS environments 24×7.
WD Red Pro drives deliver the performance, scalability and reliability businesses need for storage,< br />share and collaborate on large amounts of data on NAS systems optimized for multiple RAID bays.

Optimized for NAS with NASware™
Exclusive Western Digital NASware™ technology fine-tunes drive parameters
to match NAS system workloads, helping to increase performance and reliability.

Designed for continuous operation
WD Red Pro hard drives are designed to handle the rigorous demands of high-intensity 24x7 multi-user NAS environments and increase system durability.

Tested for reliable compatibility
Western Digital works with a wide range of NAS 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 prevent disruptions caused by increased vibration.
By dispersing excess vibration throughout the chassis of the drive, turbulence is reduced to a minimum, performance is maintained and the drives are protected.

Built for shock absorption
WD Red Pro hard drives include a multi-axis shock sensor to detect subtle shocks
and automatic compensation with dynamic flight height technology to further protect drives in NAS enclosures.

Designed with industry-leading technology
WD Red Pro 22TB hard drives feature Western Digital's proprietary OptiNAND™ technology
which leverages on-board iNAND flash to perform key maintenance functions,
releasing more capacities and improving the overall performance of the drive.

Backed by world-class support and warranty
As an industry-leading hard drive manufacturer, Western Digital stands behind its
NAS storage solutions with a 5-year limited warranty and world-class support services for data storage without problems.

Desktop Drives vs. WD Red® Pro
It is important to choose a drive that is purpose-built for RAID-optimized NAS systems
to ensure optimal performance and preserve your valuable data. Consider the following 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 that fine-tunes drive parameters
to match NAS system workloads for optimal performance.
• Reliability: Desktop drives are typically not designed for the demands of an always-on NAS environment.
WD Red Pro hard drives are designed to perform under harsh conditions in high-intensity 24x7 multi-user NAS environments.
• RAID ready: WD Red hard drives are designed with RAID error recovery control,
which helps reduce errors in multi-bay NAS systems, unlike most desktop drives that are configured for general use.
• Noise and Vibration Isolation: Designed to operate independently,
desktop drives typically offer little or no noise and vibration protection present in the system with multiple drives.
WD Red hard drives include Rotation Vibration (RV) sensors that predict and proactively preventinterference
caused by increased vibration often found in multi-bay NAS systems.
