Based on its Proven Third-Generation HelioSeal Platform, the HGST Ultrastar® He10 is the World’s First Drop-in Ready 10TB HDD Engineered for the Lowest Power with the Best Reliability for Massive Capacity Enterprise Workload Applications

SAN JOSE, Calif., December 2, 2015 – Helping the world harness the power of data, Western Digital Corporation (NASDAQ: WDC), today announced that it is now shipping the world’s first 10TB perpendicular magnetic recording (PMR) hard disk drive (HDD). As the first 10TB drop-in ready HDD, the HGST Ultrastar He10 HDD provides the highest capacity, lowest power consumption per TB and the highest reliability rating of all HDDs on the market. This is WDC’s third-generation helium drive, which defines the best enterprise-capacity hard drive in the industry.

The Ultrastar He10 HDD is the fundamental building block to address growing data needs. WDC expects its 10TB drives to be a key enabler of video, photo, business and other cloud-based applications, and will be a cornerstone for public and private cloud deployments moving forward.

Essential for creating high-density storage solutions, the Ultrastar He10 offers a 25% increase in capacity over the previous generation and uses 56% fewer watts/TB than traditional air-filled HDDs, allowing data center architects to achieve new levels of eco-environmental efficiency. The Ultrastar He10 also continues HGST’s best-in-class reliability standards, offering a 2.5 million mean-time-between-failures rating as well as a five-year warranty. It is available to all enterprise customers as a bare drive, and will be available in HGST’s Active Archive System for customers that require a petabyte-scale object storage system.

“Our HelioSeal platform has defied next-generation expectations around capacity, reliability and power in HDDs,” said Brendan Collins, vice president of product marketing, HGST. “We were the first to recognize the benefits of Helium and have pushed the boundaries while others are scrambling to catch up. The Ultrastar He10 represents the third generation of our HelioSeal line.  It redefines enterprise capacity HDDs, showing the industry where storage devices need to go, to stay in front of the future that data growth is hurtling towards.”

“Netflix has built an industry-leading Content Delivery Network and these 10TB drives will allow us to quickly integrate, build more capacity and stream more movies to our consumers,” said David Fullagar, director of content delivery architecture, Netflix. “We’ve been using the HGST HelioSeal drives for a long time and not only do they give us more capacity, they have contributed to a lower overall power envelope and higher storage density, which has allowed us to maximize our data footprint and create a network that is optimized for TCO.”

“We’re living in a trillions of sensors world, and the more data history we have, the better. Our ability to process data at scale with a low dollar per terabyte, the industry is well positioned to leverage IoT and sensor technology to build safer and smarter cities, improve homeland security, and enable customers to gain a competitive advantage with data,” said Blair Barbour, president and CEO, Photon-X. “HGST is pushing the boundaries with capacity in devices and systems, creating an innovation inflection point in the world of IoT.”

“HGST continues to lead the industry in delivering the next highest capacity hard drive for enterprise applications, beginning with 4TB, then 6TB, 8TB, and now 10TB capacity-optimized enterprise HDDs,” according to John Rydning, IDC’s research vice president. “HGST’s new Ultrastar 10TB He10 will help address the need for higher capacity, and higher density storage racks in enterprise datacenters.”
