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 Ultrastar DC HC530 hard drive. Built using HelioSeal technology, the fifth generation helium platform and the basis for the 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 a cost-efficient infrastructure. HelioSeal technology is key to achieving higher drive capacities, higher reliability ratings and extreme power efficiency for lower levels of total cost of ownership (TCO) for cloud and enterprise customers.
