Immediate Source of Acquisition
Gift of Hitachi Global Storage Technologies, 2010.
Hitachi Global Storage Technologies was founded in 2003 as a merger of the hard disk drive businesses of IBM and Hitachi.
The company specializes in computer storage products, such as hard disk drives, solid-state drives, and external storage devices.
In 2012, Hitachi Global Storage Technologies was acquired by Western Digital, and its name was changed to HGST, Inc.
Hitachi Global Storage Technologies staff maintained a hard disk drive historical collection, which was stored in the historical
records storage room at the company until it was donated to the Computer History Museum in 2010.
