Hitachi Ultrastar He6 0F18370 / HUS726060ALS640 6000GB / 6TB 7.2K SAS Hard Drive - Brand New

Hitachi Ultrastar He6 Enterprise Hard Drive

  • World’s first helium HDD – Patented HelioSeal™ technology enables this new building block for future growth
  • Industry’s first 6TB HDD – Innovative 7Stac™ disk design enables the world’s highest capacity
  • TCOptimized™ platform – Delivers higher capacity, lower power, cooler and quieter operation in a standard 3.5-inch form factor

Innovation for Next-generation, High-density Data Centers

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 offers a 50% capacity gain and still reduces the energy needed to run the drive by up to 23%

TCOptimized - Driving Down Data Center TCO with Helium

The amount of data that companies need to store is growing exponentially, but IT budgets remain flat. With 6TB, a low 5.3 idle watts, a reduced weight of 640g, and running at 4-5°C cooler, the new Ultrastar He6 lowers data center TCO on virtually every level. Key TCO benefits when compared to a typical 3.5-inch, five-platter, air-filled 4TB drive include:

  • 50% More Capacity
  • 23% Lower Idle Power
  • 49% Better Watts/TB
  • 30% Quieter Operation
  • 4° Cooler Operation
  • 50g Lighter Weight
