The 6TB Ultrastar He6 would be a good fit for cloud storage, massive scale-out environments, disk-to-disk backup, and replicated or RAID environments

HGST, a Western Digital company (NASDAQ: WDC), has announced that it is now shipping the 6TB Ultrastar He6 hard disk drive (HDD). Revealed in September 2012, HGST’s cutting-edge HelioSeal platform provides a path for higher capacity storage for decades to come while significantly lowering power consumption and customer total cost of ownership (TCO).

Leveraging the inherent benefits of helium, which is one-seventh the density of air, the new Ultrastar He6 hard drive would be a good fit for cloud storage, massive scale-out environments, disk-to-disk backup, and replicated or RAID environments.

Main platform for new technologies

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.

With 6TB, a low 5.3 idle watts, a reduced weight of 640g, and running at 4 to 5°C cooler, the new Ultrastar He6 would lower data center TCO on virtually every level. Key TCO benefits when compared to a 3.5-inch, five-platter, air-filled 4TB drive would include:

  • Highest Capacity HDD on the Market; 6TB, Seven-disk Design, Providing a low 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
