Engineered to handle high-intensity workloads with proven technologyUltrastar 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 TechnologyThe 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 CostsWestern 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 integrationLeveraging hardware designs from generations of highly successful products ensures easy qualification, seamless integration and rapid adoption by existing customers.Reliability You Can TrustBuilt 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 PowerWestern 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 HeliumThe 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 & ShockDisturbances 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 SupportAs 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.

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 it’s 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.
