HGST delivers the world's first hermetically sealed, helium hard drive, the Ultrastar He6 for massive scale-out envi- ronments. Why does helium make a di erence? 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 disks, cuts power consumption and results in a lower temperature within the disk drive. The reduction in turbulence for the spinning disk allows HGST to deliver 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 o er a 6-terabyte capacity. This design provides a 50% capacity gain and still reduces the energy needed to run the drive by up to 23%.
