Ultrastar DC HC530 14TB

Delivering the highest capacity to conquer the data explosion. 


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.

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.

Netflix Runs on HelioSeal Technology

We’re saving about 90 watts per appliance with helium drives. This savings is significant when you’re talking about thousands of streaming appliances. — David Fullagar, Director of Content Delivery Architecture, Netflix
