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.Seven-disk design, providing the best TCOLowest power consumption with best watts-per-TB- 23% lower idle power per drive- 49% better watts-per-TBBest density footprint in a standard 3.5-inch form factor- 50% higher capacityLighter weight than a standard five-disk 3.5-inch drive- 50g lighter even with two more disks, offering 50% more capacity- 38% lower weight-per-TBApplications/EnvironmentsHigh-density data centersMassive scale-out data centersContainerized data centersNearline storage applicationsBulk storageEnterprise and data center applications where density and capacity are paramount
