Driving Up Capacity and Driving Down TCO for Cloud and Enterprise Data Centers

The breadth and depth of big data is driving the universal need for higher capacities across a broad spectrum of applications and workloads. Laying the foundation for a worryfree data center, Western Digital delivers capacity to conquer the data explosion–the 14TB Ultrastar® DC HC530 hard drive.
Built using HelioSeal technology, the industry’s only fifthgeneration helium platform and the basis for our high-capacity DC HC500 series, Ultrastar DC HC530 was designed for public and private cloud environments where storage density, Watts/TB and $/TB are critical parameters for creating the most cost-efficient infrastructure.
