Storage Drives

World's first 11-disk CMR HDD platform for increased storage density.

Ultrastar Data Center HC590 hard drives combine field-proven designs with the latest innovative technologies to meet data center demands for increased storage density in the existing storage footprint.

Future of More. Plus One

The world's first 11-disk CMR HDD platform delivers unbeaten capacity of up to 26TB to help quench customer's insatiable demand for increased storage density in the existing storage footprint.

Rapid Qualification and Rock Solid Reliability

Leveraging field-proven hardware and firmware designs from generations of highly successful products ensures easy qualification, seamless integration and rapid adoption while maintaining superior dependability and reliability.

Maximum Rack-Space Efficiency

The higher storage density provided by 11 disks combined with our energy-assisted Perpendicular Magnetic Recording (ePMR) technologies, which increase tracks-per-inch (TPI), allow data centers to maximize their storage efficiency.

Protected Against Vibration & Shock

Our exclusive Rotational Vibration Safeguard (RVS) uses dual sensors to anticipate and counteract disturbances, maintaining peak performance in high-vibration environments. Combined with Dynamic Fly Height technology, Western Digital offers exceptional drive reliability and protection from unexpected shock events.

Engineered with Industry-Leading Technology

Western Digital's proprietary OptiNAND™ technology leverages integrated iNAND® embedded flash to perform key housekeeping functions, freeing up more capacity and improving the overall drive performance.

Powerful Performance and Resiliency

Choose ArmorCache™ write cache disabled (WCD) mode for increased random write performance or select write cache enable (WCE) mode to protect cached data in case of Emergency Power Off (EPO) or unexpected power loss scenarios.

Meet Eco Goals with Helium

Choose ArmorCache™ write cache disabled (WCD) mode for increased random write performance or select write cache enable (WCE) mode to protect cached data in case of Emergency Power Off (EPO) or unexpected power loss scenarios.

Trusted Reliability, Quality and World-Class Support

As an industry-leading hard drive manufacturer, Western Digital stands behind their Ultrastar hard drives with the assurance of a projected 2.5M-hour MTBF rating, a 5-year limited warranty and world-class support services to help create environments for data to thrive.

Laying the foundation for a worry-free data center, HGST delivers capacity to conquer the data explosion - Ultrastar® He12 HDD. Designed to handle workloads up to 550TB per year, the Ultrastar He12 HDD is the industry's first 12TB drive and uses PMR technology to make it drop-in ready for any enterprise-capacity application or environment. The stable internal environment created by fourth-generation HelioSeal® technology enables a new 8-disk design, increasing the capacity by 20% when compared to the 7-disk design of the prior generation. This highest capacity helium drive offers the lowest power profile in the industry to help data center architects meet eco-environmental goals and requirements. Targeted at 2.5M hours MTBF, the Ultrastar He12 HDD provides the highest reliability rating available of all HDDs on the market today by building on the successful design of its 10TB, 8TB and 6TB predecessors. Trust HGST and the Ultrastar He12 HDD to deliver more capacity, more efficiency, more reliability and more value to your data center.
