NAS for Big Business
Increase the efficiency and productivity of your business with WD Red Pro hard drives for up to 16 bay NAS system. WD Red Pro comes equipped with NASware 3.0, which increases system compatibility allowing for seamless integration with your existing network infrastructure. Add value to your business by enabling your employees to quickly share their files and back up folders reliably with WD Red Pro NAS hard drives 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 for optimum NAS compatibility
Desktop drives aren't purpose-built for NAS. But WD Red Pro drives with NASware are. Our exclusive technology takes the guesswork out of selecting a drive and balances performance and reliability in NAS and RAID environments. Simply put, WD Red Pro is the most compatible drive available for medium to large NAS enclosures. But don't take our word for it. WD Red Pro is a reflection of the most extensive NAS partner compatibility-testing list that is available on the market.*
Compatibility list as of March 2016
Larger NAS Bay Shock Protection
WD Red Pro is 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 1 to 16 bay NAS environments and helps increase hard drive reliability.
Disk Utilities and Migration Tools
Acronis True Image WD Edition can clone drives, backup your operating system, applications, settings and all of your data, while also having the ability to securely wipe any data you no longer need. You can quickly and easily deploy a new hard drive to your PC or laptop and automatically migrate your operating system, applications, and all of your important data, including images, music, and documents.
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.
Extended Drive Testing
A NAS environment that has up to 16 bays is very demanding on a hard drive with added vibration, heat and other factors. This is why every WD Red Pro drive is shipped with extended thermal cycle burn-in testing which ensure each drive for extended reliable operation.
In combination with 3D Active BalanceTM Plus, WD Red Pro also features hardware vibration compensation technology which monitors the drive to correct both linear and rotational vibration in real time, further increasing drive reliability.
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, which prevents the drive from fallout in RAID applications.
Longer Warranty Coverage
Complementing WD Red at a 3-year limited warranty, WD Red Pro offers longer warranty coverage with a 5-year limited warranty for an even greater peace of mind.
Specifically designed and tested for medium to large business NAS applications with up to 16 bays.
For systems that use less than 8 bays, please consider WD Red hard drives.*

WDs exclusive NASware technology, built into every WD Red hard drive.
WDs exclusive NASware technology, which is built into every WD Red hard drive, improves NAS storage performance by reducing common hard drive concerns in NAS systems including concerns for things like compatibility, integration, upgradeability, reliability and cost-of-ownership that are experienced with a hard drive designed for desktop computers.
Desktop hard drives are designed for desktop computers. WD Red = NAS.
Desktop hard drives are designed for optimum performance and reliability in a desktop personal computer. Although they are an affordable alternative to enterprise-class drives, desktop drives have a higher level of risk for potential data loss and failure in an always-on RAID configured NAS system. Specific issues that you may experience using desktop drives in a NAS or RAID environment include:
Compatibility: Desktop hard drives are not always tested for compatibility in NAS and can present problems during integration.
Reliability: Most desktop drives are not designed for the high operating temperatures or for 24x7 operating environments making them less reliable when used in a NAS system.
Error recovery controls: Desktop drives are not traditionally designed for RAID environments and have controls that prevent the RAID controller from assisting in the event of an error which can cause the hard drive to drop off the RAID after a period of time. Rebuilding a RAID often requires several hours and can have a significant impact on downtime and productivity.
Noise and vibration: Typically designed for single drive applications, average desktop drives are not optimized for multi-drive systems which have higher noise and vibration levels. When these drives are added to a NAS, the additional vibration can reduce the reliability and life span of the drive.
Beyond the Desktop with NASware
WD Red drives include WD's exclusive NASware technology that addresses many of the challenges a traditional desktop hard drive has in a NAS system. WD works directly with our partners to test compatibility and reduce our customer's guess work as to which drive is right for their NAS system. Designed to deliver a better customer experience in small NAS systems, this innovative firmware finely balances the most important attributes of performance, power, and reliability in multiple drive environments. The unique algorithms in NASware optimize power and performance without compromising on the attributes that NAS-system owners value.
Save power and money
NASware further improves drive reliability and protects your data in the event of a power loss or disruption. Optimized power usage of WD Red drives results in significant power savings and lower hard drive operating temperatures within a small NAS environment, improving the overall reliability and performance of the drive and reduces the NAS cost of ownership.
Intelligent Error Recovery
With built in intelligent error recovery controls, NASware also prevents hard drives from being dropped off the RAID due to extended error recovery. This feature provides more availability and less down time when rebuilding the RAID.
To further improve reliability, NASware minimizes the data corruption or loss in the event of an unexpected power loss by completing the command in process before shutting down.
Important Features for System Integrators
In addition to features that make WD Red drives perfect for populating or upgrading NAS systems, NASware brings features that system integrators need when building specialized NAS systems.
Streaming Support - NASware provides built-in compatibility with the ATA Streaming Feature Set, which is important for AV storage applications such as Windows Media Center.
SMART Command Transport (SCT) support - NASware allows monitoring and measuring of drive performance via the SMART command set. SMART can return data like thermal profiles, drive access statistics and more. NASware also delivers temperature accuracy within 1°C.
Power Management Support - Enables optimized power usage within the NAS system and protects your data in the event of a power loss or disruption.
BIC Performance - Optimized seek to provide BIC performance while reducing the power and acoustics.
