Desktop Drives vs. WD Red™ Plus
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™ Plus drives are.
- Error Recovery Controls: WD Red™ Plus 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™ Plus drives are designed to thrive in multi-bay NAS system environments.

Description

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 workloads 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 3.0’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 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.

Description

20TB capacity with a reimagined HDD
An innovative storage architecture to help our customers meet their need for exponential data growth.

Reimagining the HDD for Exponential Data Growth
Hyperscale cloud, CSPs, enterprises, smart video surveillance partners, NAS suppliers and more need storage solutions to meet the exponential growth in data creation. When it comes to cost-effective storage of data at scale, hard disk drives (HDDs) continue to play a central role. HDDs deliver the capacity, performance and reliability needed to store vast amounts of data today and well into the future. Investments in HDD technology remain critical to supporting worldwide data growth.

Western Digital has developed flash-enhanced drives with OptiNAND™ technology by vertically integrating our leading NAND flash with our world-class HDDs. Western Digital HDDs have been leaders in areal density with industry first technologies of energy-assisted magnetic recording technology (EAMR), triple-stage actuator (TSA), HelioSeal®, and now OptiNAND technology. Higher areal density means higher capacities to meet storage challenges.

20TB1 HDDs with OptiNAND Technology
OptiNAND integrates an iNAND® Universal Flash Storage (UFS) Embedded Flash Drive (EFD) with traditional spinning disk media, and incorporates innovative changes to the firmware algorithm and system-on-a-chip (SoC). OptiNAND is not a hybrid technology. The drive works smarter, with enhanced firmware algorithms taking advantage of expanded metadata that has been offloaded to the iNAND, enabling more tracks per inch (TPI) with resulting increased areal density.

The Ultrastar DC HC560, with the first implementation of OptiNAND technology’s capacity-enabling features, delivers an unbeaten 20TB capacity in a nine-disk platform (2.2TB/platter) with CMR recording format
