The Ultrastar 10TB SMR HelioSeal will be based on seven platters of 1.43TB. In order to achieve the large amount of platters and the high capacity, the drive will be filled with Helium. Helium is lighter than “regular” air and therefore reduces mechanical power dissipated in air shear and allows the platters to be closer to eachother. The drives are also more energy efficient, thanks to the Helium less motor power is required.

The drive is mainly targeted for static data that isn’t frequently accessed. Specifications such as the rotations per minute (RPM) and data transfer speeds haven’t been announced yet.
