Handle Data Center Workloads with Proven Technology
The combination of field-proven hardware with the latest innovative technologies delivers the performance, capacity, and reliability needed to handle high-intensity workloads in 24/7 multiuser data center environments.
Grow Capacity while Lowering Costs
Western Digital's energy-assisted perpendicular magnetic recording (ePMR) technology enables customers to grow capacities while lowering TCO (total cost of ownership), including both $/TB and OpEx.
Rapid Qualification and Integration
Combining hardware designs from generations of highly successful products with Conventional Magnetic Recording (CMR) technology ensures easy qualification, seamless integration, and rapid adoption by existing customers.
Reliability You Can Trust
Built off the same platform that is deployed in thousands of data centers around the world, these drives deliver superior dependability and field-proven reliability for hassle free data storage.
Increase Density with Low Power
Western Digital's Triple-Stage Micro Actuator increases tracks per inch (TPI), while providing greater control over the actuator arm, enabling the highest capacities with low power.
Meet Eco Goals with Helium
The stable internal environment created by HelioSeal technology enables this high-capacity helium drive to deliver one of the lowest power profiles in the industry.
Protected Against Vibration & Shock
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.
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 2.5 million hour MTBF rating, a limited 5-year warranty, and support services to help create environments for data to thrive.
