37 TB capacity and 23% lower power consumption. That’s the power of helium. Introducing the Ultrastar He8, the second generation of HGST hard drives based on the widely recognized and proven HelioSeal platform. Now available. With capacities of 8 TB and 6 TB, the Ultrastar He8 surpasses any other air-driven hard drive and sets the standard for capacity and energy efficiency in cloud and hyperscale data center environments. We understand the growing pressure that data centers face. Volumes are increasing, operating costs are rising, but budgets remain constant. Reducing total cost of ownership (TCO) has become the focus for data center architects. Thanks to HGST's patented HelioSeal process, the Ultrastar He8 offers the best solution in terms of TCO, delivering the highest capacity in the industry at 8 TB, a low idle power consumption of just 5.1 watts, a reduced weight of 650 g, and operating temperatures that are 4 to 5 °C cooler. Cooler and quieter with industry-leading performance efficiency (Watt/TB), the Ultrastar He8 lays the foundation for future growth in massive scale-out environments.
