It's ideal for power computing applications such as multimedia, video and photo editing, and maxed out gaming computers.

Inspiring performance and capacity Inspiring performance and capacity

For the creators, the gamers and those that demand the best, we delivered the next generation of hard drives to enlarge your PC playground. The latest WD Black desktop hard drives offer enhanced features that maximise system performance, allowing you to spend more time doing what you love most and less time waiting. WD Black is designed to intensify your PC experience with generous capacity and incredible performance, pushing the boundaries of personalisation.

For the Gamer

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

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 stabilises 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

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 maximise drive performance. Adding additional value, WD's Dynamic Cache Technology increases performance by improving caching algorithms in real time and optimising 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 optimising 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
The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.

Tested for compatibility
We perform tests on hundreds of systems and a multitude of platforms in our FIT Lab™ to give our customers confidence that our drives will work in their systems.

Industry-leading 5-year limited warranty
Our engineers have a relentless dedication to keeping your data safe. This passion is reflected in the industry-leading 5-year limited warranty we stand behind on all WD Black drives. The evidence for our success lies in our capability to continually deliver next-generation technologies and in our ability to stand behind these products with industry-leading 5-year limited warranty coverage. WD Black is tested to a higher standard than conventional hard drives with more strenuous and aggressive testing over a longer period of time. This is our story of innovation, refinement and passion for performance hard drives.

Recommended use:
WD Black hard drives are tested and recommended for use in PCs, high-performance workstations, all-in-one PCs, gaming PCs, game consoles, home media PCs and notebook computers.*

* Desktop drives are not recommended for use in RAID environments, please consider using WD Red hard drives for home and small office, 1 to 5 bay NAS systems and WD datacenter hard drives for 6 bay and greater NAS systems.
1 Not all products may be available in all regions of the world.
2 As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 3 Gb/s transfer rate calculated according to the Serial ATA specification published by the SATAIO organisation as of the date of this specification sheet.
