Western Digital added helium-filled hard disk drives to the Red, Red Pro and Purple product lines. The disks drive new consumer storage devices with increased capacity, cooler operation and higher density.
HGST, now a subsidiary of Western Digital, first released HelioSeal Technology in 2014. Not long after, the company claimed 1 million products shipped and field reliability increased a full 15 percent. Helium allows hard disk manufacturers to use more platters (up to 7 in a drive) to increase density. The gas is thinner than regular air so the platters face less resistance in motion. This reduces vibration and friction heat inside the drive, and it uses less power at the motor.
Western Digital will release helium-filled products using technology from HGST. These drives will make it into WD-branded consumer models like the My Book and several NAS systems.

We expect helium-based hard disk drives to spread into other markets. Recently, Google pitched hard disk manufacturers to increase the z-height of disk drives to create products with more platters. This would increase storage capacity per disk and reduce costs. The fixed priced components like the case and motor would stay relatively unchanged but allow more platters that increase device storage density.
