HGTST announces Ultrastar 10TB Helium filled hard disk

Western Digital’s subsidiary HGST has announced it will start production of Helium filled 10TB HDDs in the first quarter of 2015. The drives are targeted at enterprise usage and after production in the first quarter of next year, they should become available for purchase at the end of the second quarter of 2015.


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.
