Western Digital WUH721414ALE6L4 Ultra Star DC - 14TB



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 industrys 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.

Solves TCO Challenges

  • High Capacity - Up to 14TB HDDs, drop-in ready for Big Data workloads
  • Low Power - Up to 58% lower idle W/TB than 8TB Ultrastar air-filled drives
  • More Reliable - 25% higher MTBF rating than air-filled HDDs


  • 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

Applications and Workloads

  • Cloud & Hyperscale Storage
  • Massive Scale-Out (MSO), high-density data centers
  • Distributed File Systems
  • Bulk storage using Object storage solutions like Ceph™ and OpenStack Swift
  • Primary and secondary storage for Apache Hadoop® for Big Data Analytics
  • Surveillance Analytics

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