Driving Up Capacity and Driving Down TCO for Cloud and Hyperscale 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 worry-free data center, Western Digital delivers the capacity to conquer the data explosion with the Ultrastar DC HC500 series of hard drives. Built using HelioSeal technology, the industry’s only fifth-generation helium platform, the DC HC500 series is

designed for public and private cloud environments, where storage density, Watts/TB and $/TB are critical for creating the most cost-efficient infrastructure. HelioSeal technology is key to achieving higher drive capacities, greater reliability ratings and extreme power efficiency. The result is a lower Total Cost of Ownership (TCO) for our cloud and enterprise customers.

Beyond Air. Helium Takes You Higher.

Responding to the complex needs of the modern data center, Western Digital has developed HelioSeal technology, a foundational building block for high-capacity hard disk drives (HDDs). This innovative technology hermetically seals the HDD and replaces the air inside with helium, which is one-seventh the density of air. The less dense atmosphere resets the boundaries and challenges of conventional high-capacity Higher Capacity

HDDs, allowing for dramatic increases in efficiency, reliability and value.
