Helium Makes You Sound Funny, Makes Hard Drives Work Better

Helium, the lighter-than-air gas used to make party balloons float and to let us talk in a funny voice has another use: allowing hard disk drives to run cooler and more efficiently. Western Digital believes their technology will allow more platters per drive, higher data density and lower drag on the drive heads (which "fly" over the surface of the platters at ridiculously tiny distances). The drives are evacuated, filled with Helium, and hermetically sealed.
