Ultrastar DC HC500 Series
Solves TCO Challenges

Western Digital Ultrastar DC HC500 Series

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

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.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


    • Up to 14TB capacity in a standard 3.5-inch form factor
    • Conventional Magnetic Recording (CMR) technology works seamlessly in capacity enterprise environments
    • Reliable, field-proven design across five generations
    • HelioSeal design delivers power efficiency (Watts/TB)
    • 2.5M hours MTBF rating and a 5-year limited warranty
