Seems Western Digital is working on a new line of super-duper disk drives that'll be sealed, and filled with helium.
Back in the day, at my first Real Job, we had a minicomputer - a Keronix Nova clone, if memory serves - that had a high-performance disk drive. A head per track it had, so seek time was zero, and that dome that contained the thick platter, the heads, and the motor was filled with helium.
Didn't store a lot of bits, but it sure was fast. Good for storing program overlays (on a machine with a 32Kx16 address space).
