HGST delivers the world's first hermetically sealed, helium hard drive, the Ultrastar He6 for massive scale-out environments. Why does helium make a difference? Helium has only one-seventh the density of air. Replacing air with helium inside a hard drive dramatically reduces the turbulence caused by the spinning disk, cuts power consumption and results in a lower temperature within the disk drive.
The reduction in turbulence for the spinning disk allows HGST to offer a seven-disk design in a traditional 3.5-inch form factor. In addition to being the world's first helium-filled hard drive, HGST Ultrastar He6 is also the first hard drive in the industry to offer a 6-terabyte capacity. This design delivers a 50% capacity gain and still reduces the energy needed to run the drive by up to 23%
