Wd Red Pro Wd121Kfbx 12Tb 7200 Rpm 256Mb Cache Sata 6.0Gb/S 3.5" Internal Hard Drive

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 3.0’s 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 don’t 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 drives 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 drives 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 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 aren’t 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.
