WD 12TB Red Pro WD122KFBX NAS 3.5" SATA 7200rpm 512MB Cache HDD

Optimized for NAS with NASware™
Western Digital's proprietary NASware™ technology adjusts drive parameters for NAS system workloads, helping to improve performance and reliability.

Built for continuous work
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 reliable compatibility
Western Digital works with numerous NAS system vendors to conduct extensive testing to ensure the drive's compatibility with most NAS enclosures.

Excessive vibration protection
WD Red Pro hard drives feature a rotational vibration (RV) sensor that predicts and proactively cancels interference caused by new vibrations. By dispersing unwanted vibrations throughout the hard drive chassis, turbulence is minimized, maintaining performance and protecting the hard drive.

Designed to absorb shock
WD Red Pro hard drives include multi-axis shock sensors that detect subtle vibration events and automatically compensate using dynamic suspension height technology to further protect the drive in the NAS chassis.

Designed with industry-leading technology
WD Red Pro 22TB and 24TB hard drives feature Western Digital's proprietary OptiNAND™ technology, which utilizes an integrated iNAND embedded flash drive to perform critical cleanup functions, freeing up more capacity and improving overall drive performance.

Backed by world-class support and warranty
Western Digital, the industry's leading hard drive manufacturer, backs its NAS storage solutions with a 5-year limited warranty and world-class support for effortless data storage.

Desktop Hard Drives vs. WD Red® Pro Hard Drives <br>It is important to select a drive that is purpose-built for a RAID-optimized NAS system to ensure optimal performance and preserve valuable data. Consider the following factors when choosing a hard drive for your NAS:
• Compatibility: Unlike desktop drives, WD Red Pro drives are designed and tested specifically for NAS and feature NASware™ technology, which adjusts drive parameters for NAS system workloads for optimal performance .
• Reliability: Desktop hard drives are generally not built for the rigors of a 24/7 NAS environment. WD Red Pro drives are designed to operate under demanding conditions in high-intensity, 24/7 multi-user NAS environments.
• RAID support: WD Red hard drives feature RAID error correction control to help reduce failures in multi-slot NAS systems, unlike most desktop hard drives that are set up to be general-purpose.
• Noise and vibration protection: Desktop hard drives are designed to operate independently and often offer little or no protection against the noise and vibration encountered in multi-drive systems. WD Red drives feature rotational vibration (RV) sensors that predict and proactively counteract vibration-induced disturbances common in multi-drive bay NAS systems.
