The Deskstar is the name of a product line of computer hard disk drives. It was originally announced by IBM in October 1994. The line was continued by Hitachi when in 2003 it bought IBM's hard disk drive division and renamed it Hitachi Global Storage Technologies. In 2012 Hitachi sold the division to Western Digital who continued the drive product line brand as HGST Deskstar. In 2018 Western Digital began winding down the HGST brand and as of 2020 it is defunct.
