This has been achieved with the aid of a cooling system run on superfluid helium, more than 2, 000 litres of which were loaded into the telescope at launch.

This reduction in power and associated cooling cost significantly contributes to the lower TCO of the helium-filled platform.

In addition, the inherent benefits of the platform, including the helium fill, allow HGST to significantly improve datacenter TCO on virtually every level: capacity, power, cooling and storage density.
