Helium-filled hard drives have a number of mechanical advantages compared to traditional HDDs, but they are also more expensive to manufacture. Western Digital subsidiary HGST introduced the world’s first commercial helium-filled hard drive in 2013, targeting datacenters. Since then, the company has launched two more generations of its helium drives, including two models with 10 TB capacity. This week Western Digital unveiled the world’s first family of helium-filled HDDs designed for consumer applications, which will be sold under the WD brand.
