For the Gamer For the Enthusiast For the Creative Pro

For the Gamer...

Smarter than the average drive
Performance and workstation PCs equipped with high-end components often emit vibrations and acoustics that can reduce the precision and performance of your hard drive. Even the best chassis on the market cannot always compensate against this. The new generation of WD Black hard drives feature Vibration Control Technology (VCT) which allows the disks inside the drive to adapt to any mounting problems or vibration conditions that are inside your case, resulting in increased data accuracy, performance and reliability over time. Put simply, this means you can game harder, faster and longer.

For the Enthusiast...

Action meets stable traction
In addition to Vibration Control Technology (VCT), WD Black is also equipped with StableTrac Technology, which secures the motor shaft inside the drive at both ends to help reduce additional system-induced vibrations. StableTrac confidently stabilizes the platters inside, resulting in more accurate tracking in a particular sector during read and write operations and delivers increased performance.
(2 TB models and above).

For the Creative Pro...

High resolution for a high definition world
Underlying its athletic stance of performance and capacity, WD Black features a new High Resolution Controller (HRC) with an improved architectural design, resulting in increased data precision across the hard drive. This translates to superior responsiveness evolving your high definition world to the next level.


Product Features:

Protecting your moments
The worst thing that can happen during a rendering process is losing data due to power fluctuation or power failure. The new generation of WD Black hard drives is equipped with Corruption Protection Technology (CPT), which helps to protect and limit the potential problem of data loss during power failure or power loss to the hard drive. Overall, Corruption Protection Technology can save you time and money on your project.

Efficient dual processing
When it comes to processing power, more is always better. WD Black features a dual core processor that offers twice the processing power to maximize drive performance. Adding additional value, WD's Dynamic Cache Technology increases performance by improving caching algorithms in real time and optimizing the cache allocation between reads and writes. This results in the drive automatically allocating more cache for read data, which reduces data congestion and increases overall performance.

Maximum performance
Sophisticated performance enhancing features deliver the speed you need for demanding applications like photo and video editing and Internet gaming.

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

Dynamic Cache
WD's dynamic caching algorithm improves performance in real time by optimizing cache allocation between reads and writes. For example, if there's an overwhelming percentage of read traffic as opposed to write traffic, the drive automatically allocates more cache for read data, which reduces congestion and improves overall drive performance.

Rock-solid mechanical architecture
Enhanced reliability features help protect the drive and the data stored on it.

StableTrac™
The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations which enables consistently higher performance. (2 TB and 1.5 TB models only)

NoTouch ramp load technologyNoTouch™ ramp load technology

Choose a drive that is designed and engineered for home and business surveillance systems and enjoy the peace-of-mind you can only get from a surveillance-class hard drive.

Desktop drives vs. surveillance-class storage
You wouldn’t use a bicycle to transport cargo across the country because it’s not the right tool for the job. You also shouldn’t use a desktop hard drive in your surveillance security system because it wasn’t designed for that application.

WD Purple surveillance-class storage has been tested to be compatible in a wide-range of security systems. These drives are designed to replace standard desktop drives that were not designed for the harsh 24/7 always-on, high-definition surveillance environment. Desktop drives are built to run for only short intervals and are not engineered to withstand high-temperature fluctuations and equipment vibrations found in a typical surveillance application.


Product Features:

WD Purple Surveillance Storage is designed for high temperature, always-on, surveillance security systems to ensure reliability and quality video play back when you need it most. Experience the security of knowing you’re using a surveillance–class drive designed by a leader in the hard drive industry.

Improve performance with AllFrame
WD Purple surveillance-class hard drives are equipped with AllFrame technology which works with ATA streaming to reduce frame loss, improve playback and increases the number of drive bays supported. AllFrame reduces video interruptions that commonly occur when desktop hard drives are incorrectly used as storage in security systems. Missed frames and lost footage is a serious problem when an event occurs and surveillance footage needs to be retrieved. WD Purple with AllFrame provides the confidence you should expect when it's time to play back and review critical surveillance footage.

Engineered for compatibility
WD Purple surveillance hard drives are built for compatibility with industry-leading chassis and chip set manufacturers for seamless integration into your new or existing video surveillance system.
