Swimming Storage: Helium Hard Drives Use Immersion Cooling

Western Digital’s HGST unit announced a new Helium-filled hard drive, which boosts storage capacity by reducing drag, since helium has one-seventh the density of air. This allows HGST to place spinning disks closer together, and pack seven disks into a drive that normally would hold five. Since the HelioSeal drive is hermetically sealed, it also makes it ideal for immersion cooling.
