Description

Engineered to handle high-intensity workloads with proven technology

Ultrastar Data Center HC555 hard drives are engineered to deliver the large capacity, strong performance and proven reliability needed to handle high-intensity workloads in 24×7 multi-user data center environments.

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 multi-user 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
Leveraging hardware designs from generations of highly successful products 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 Actuator (TSA) 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 our HelioSeal® technology enables this high-capacity helium drive to deliver one of the lowest power profiles in the industry.

Protected Against Vibration & Shock
Disturbances caused by increased vibration are anticipated and proactively counteracted by Rotation Vibration (RV) sensors and subtle shock events are automatically detected by multi-axis shock sensors and compensated for with dynamic fly height technology to maintain performance and protect data.

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.
