HGST Ships 6 TB Ultrastar He6 Helium-Filled Hard Drives


HGST, a Western Digital company, today announced that it is shipping the 6 TB Ultrastar He6 hard disk drive (HDD). Key OEM, cloud and research leaders working closely with HGST to qualify the drive include HP, Netflix, Huawei Unified Storage, CERN, Green Revolution Cooling and Code42, as well as some of the world's largest social media and search companies. 

Revealed in September 2012, HGST's cutting-edge HelioSeal platform provides a path for higher capacity storage for decades to come while significantly lowering customer total cost of ownership (TCO). Leveraging the inherent benefits of helium, which is one-seventh the density of air, the new Ultrastar He6 drive features HGST's innovative 7Stac disk design with 6 TB, making it the world's highest capacity HDD with the best TCO for cloud storage, massive scale-out environments, disk-to-disk backup, and replicated or RAID environments.

Through HGST's innovative and patented HelioSeal process, the Ultrastar He6 drive is the industry's first hermetically sealed helium-filled HDD that can be cost-effectively manufactured in high volume. The breakthrough development of the hermetically sealed process is arriving just in time as key market requirements are colliding with HDD areal density constraints. According to IDC, areal density growth rates have slowed, and are expected at a rate of less than 20 percent per year from 2011 to 2016. Moving forward, HGST's helium platform will serve as the main platform for new technologies like shingled magnetic recording (SMR) and heat-assisted magnetic recording (HAMR) where HGST will continue to push the HDD areal density envelope. The helium platform will also serve as the future building block for new, growing market segments such as cold storage, a space that HGST plans to address over the next couple of years.

The amount of data that companies need to store is growing exponentially, but IT budgets remain flat. With 6 TB, a low 5.3 idle watts, a reduced weight of 640g, and running at 4-5°C cooler, the new Ultrastar He6 lowers data center TCO on virtually every level. Key TCO benefits when compared to a 3.5-inch, five-platter, air-filled 4 TB drive include:
  • Highest Capacity HDD on the Market; 6 TB, Seven-disk Design, Providing the Best TCO
  • Lowest Power Consumption with Best Watts-per-TB
  • 23 percent lower idle power per drive
  • 49 percent better watts-per-TB
  • Best Density Footprint in a Standard 3.5-inch Form Factor
  • 50 percent higher capacity
  • Lighter Weight than a Standard Five-disk 3.5-inch Drive
  • 50g lighter even with two more disks, offering 50 percent more capacity
  • 38 percent lower weight-per-TB


Data center designers and server vendors are continuing to pack more capability into smaller spaces, and with that, effective cooling is becoming a new challenge due to hotter components and less space for efficient airflow. One solution, which has been explored by many, is liquid cooling. Liquid, which is denser than air, can remove heat more efficiently and maintain a more constant operating temperature. However, traditional drives cannot be submerged as they are open to the atmosphere and would allow the cooling liquid inside, damaging or destroying the HDD. HGST's HelioSeal platform provides the only cost-effective solution for liquid cooling as the drives are hermetically sealed and enable operation in most any non-conductive liquid. Today, HGST is working with leading innovators in this space such as Huawei and Green Revolution Cooling.

The 6 TB HGST Ultrastar He6 hard drives are now generally available.
