Maximum performance.
Dual processor technology, up to 64 MB cache and SATA 3 Gb/s or 6 Gb/s interface takes everything we know about 7200 RPM performance and turns it on its ear.

No compromises.
High performance, high capacity, best-in-class reliability, and cutting edge technology make up WD Caviar Black, the ideal drive for those who demand only the best.

Award winning.
This 7200 RPM speedster is at the top of its class when it comes to performance and reliability benchmarks.

WD is leading the way with a full lineup of SATA 6 Gb/s drives.

Over the years the industry has increased bus bandwidth from PATA through SATA 1.5 Gb/s and SATA 3 Gb/s to keep up with the demand for higher transfer rates. The next evolution of bus bandwidth has now been achieved with the introduction of SATA 6 Gb/s, (SATA 3.0). We’ve added a SATA 6 Gb/s interface to our award-winning WD Caviar Blue and WD Caviar Black desktop hard drives in capacities from 250 GB to 2 TB. This transition to a SATA 6 Gb/s interface aligns with the introduction of SATA 6 Gb/s-supporting chip sets and motherboards coming to the market.

This new generation of WD RE-GP drives takes advantage of the performance improvements offered in our WD RE3 family of drives and adds advanced power management technology to deliver a faster, greener solution for large-scale data centers.

Faster - 64 MB cache, dual processors, and increased areal density yield twice the processing power results in up to 25% performance improvement over the previous generation.

Greener - Improvements in our power-conserving technologies - IntelliSeek™, IntelliPark™, and IntelliPower™ - deliver improved power consumption over our previous generation of WD RE-GP drive.

Improved rotary vibration tolerance - Advanced mechanical optimizations along with system characterization and validation provide the highest performance under vibration conditions of any WD product.

Lower total cost of ownership - Large data-hungry organizations such as financial institutions and web service providers may realize up to $10 savings per drive per year in electricity costs (U.S.). A large data center with 10,000 drives could realize up to $100,000 in saving per year.

24x7 reliability - With 1.2 million hours MTBF, these drives have the highest available reliability rating on a high-capacity drive.

IntelliPower™ - A fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance. Additionally, GreenPower drives consume less current during start up allowing more drives to spin up simultaneously resulting in faster system readiness.

IntelliSeek™ - Calculates optimum seek speeds to lower unnecessary power consumption, noise, and vibration.

IntelliPark™ - Delivers lower power consumption by automatically unloading recording heads during idle to reduce aerodynamic drag, and by disengaging read/write channel electronics.

Active Power Management - WD drives with GreenPower™ technology monitor work load and automatically invoke idle mode whenever possible to further reduce unnecessary power consumption. Drive recovery time from idle mode is less than one second, providing seamless power management between the drive and the host controller.

Perpendicular Magnetic Recording (PMR) - Employs PMR technology to achieve even greater areal density.

StableTrac™ - Secures the motor shaft at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations.

RAID-specific time-limited error recovery (TLER) - Pioneered by WD, this feature prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.

Rotary Acceleration Feed Forward (RAFF™) - Optimizes operation and performance when the drives are used in vibration-prone multi-drive systems such as rack mounted servers.

Ideal For
Large data centers, web service providers, commercial grade surveillance systems and organizations requiring huge amounts of storage with limited budget and power allotment.

With drives up to 10TB, the WD Red drive is built for single-bay to 8-bay NAS systems and packs the capacity to store your precious data in one powerhouse unit.

Cooler Temperatures

By reducing power consumption, the operating temperature of your NAS stays cool. With a lower temperature in your system, you can create a more reliable solution for your NAS.

Built for NAS Compatibility

WD Red drives with NASware technology are purpose-built to balance performance and reliability in NAS and RAID environments.

Desktop Drive vs. WD Red Drive

A desktop hard drive is not typically tested and designed for NAS environments. WD Red has features such as NAS compatibility, increased reliability and more.

WD RED. BUILT FOR NAS.

Equip your NAS with WD Red hard drives and enjoy streaming your media, backing up your PCs, sharing your files, and managing your digital content quickly and easily.

3D Active Balance Plus

Helps to ensure your data is protected from excessive vibration and noise in a NAS or RAID environment. This dual-plane balance control maintains your drive’s performance over time.

Premium Support and a 3-year Limited Warranty

Confidently upgrade to the best in NAS drive performance with the assurance of a 3-year limited warranty and world-class support services included with every WD Red drive.

24/7 Reliability

Since your NAS system is always on, a highly reliable drive is essential for long term reliability. Desktop drives are not designed and tested in 24x7 conditions, which is a foundation of WD Red NAS hard drives.

EXCLUSIVE TECHNOLOGY

Seamless integration, robust data protection and optimal performance for NAS systems under heavy demand.

WD RED FOR HOME

Stream, backup, organize and effortlessly share your digital content to your TV, PC and more. NASware technology increases your drives' compatibility with your NAS system, for better playback with your devices.

WD RED FOR SMALL BUSINESS

Businesses thrive on productivity and efficiency, two guiding principles built into the design of the WD Red drive. Share and backup files at the speed of your business with a WD Red drive in your NAS.

WD RED FOR BIG BUSINESS

Looking for maximum performance in a heavy use NAS? The WD Red Pro drive is designed to handle an increase in workload and system demand and features a 5-year limited warranty.

DESIGNED FOR NAS

Desktop drives aren't purpose-built for NAS. But WD Red drives with NASware 3.0 are. Our exclusive technology takes the guesswork out of selecting a drive. We can help you find the perfect storage for your NAS system.
