It was initially a subsidiary of Hitachi, formed through its acquisition of IBM's disk drive business. It was acquired by Western Digital in 2012, but required to operate autonomously from the remainder of the company due to conditions imposed by Chinese regulators. However, in October 2015, Chinese regulators permitted Western Digital to begin wider integration of HGST into its main business. By 2018, the HGST brand had been phased out, with its remaining products now marketed under the Western Digital name.
On March 8, 2012, Western Digital (WD) acquired Hitachi Global Storage Technologies for $3.9 billion in cash and 25 million shares of WD common stock valued at approximately $0.9 billion. The deal resulted in Hitachi, Ltd. owning approximately 10 percent of WD shares outstanding, and reserving the right to designate two individuals to the board of directors of WD. Citing antitrust concerns, China's Ministry of Commerce required HGST to operate autonomously from Western Digital, restricting outright integration between the companies' operations. As a result, HGST continued to operate independently with its own product lines and product development.
As part of the deal, Western Digital agreed to trade assets with Toshiba, with Toshiba receiving assets for the production of 3.5-inch hard drives, in exchange for a Toshiba factory in Thailand for producing 2.5-inch drives (which had been inactive since the 2011 floods).
In November 2013, HGST announced a 6 TB capacity drive filled with helium. In September 2014, the company announced a 10 TB helium drive, which uses shingled magnetic recording to improve density.
In October 2015, the Chinese Ministry of Commerce issued a decision allowing Western Digital to begin integrating HGST into its main business. WD was required to maintain the HGST brand and sale team for at least two more years. In 2018, Western Digital announced that it was phasing out its HGST brand and that all of its remaining product lines (particularly Ultrastar) will henceforth be marketed as brands of Western Digital.
