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 247 multi-user data center environments. Grow Capacity while Lowering Costs Western Digitals 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 Digitals 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.
