Western Digital Ultrastar HE6 internal hard drive 6 TB 7200 RPM 64 MB 3.5" Serial ATA III

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 TCO
Lowest power consumption with best watts-per-TB
- 23% lower idle power per drive
- 49% better watts-per-TB
Best density footprint in a standard 3.5-inch form factor
- 50% higher capacity
Lighter 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-TB
