Helium-filled hard drives reduce friction and hence allow more storage with 20% less power

Helium, the 2nd lightest element, is already used in the cooling of superconducting magnets. Helium reduces friction, vibration, and heat and thus, when utilized in hard drive design, reduces mechanical issues that limit the storage density while using 20% less power than conventional hard...
