Diagram of consolidation

At least 223 companies have manufactured hard disk drives.[1] Most of that industry has vanished through bankruptcy or mergers and acquisitions. None of the first four entrants continue in the industry today.[2] As shown in the graphic surviving manufacturers are Seagate, Toshiba and Western Digital (WD) all of whom grew at least in part through mergers and acquisitions.

Notes[edit]

  1. ^ The Bulgarian manufacturer ISOT manufactured a 10 MB harddisk drive CM 5508 in 1989. It seems to have been used in the Iskra-1030 personal computer built in 1989 as well. The CM 5508 drive was also available under the ИЗОТ name.

Retrieved 2012-12-30. Western Digital will be allowed to acquire Hitachi's 2.5" and SSD businesses, but not the 3.5" business. Instead Western Digital will be selling that business to Toshiba – factories and all – along with granting licenses for the necessary patents, which would allow Toshiba to effectively continue in the 3.5" market from where Hitachi left off. This would firmly establish Seagate, Western Digital, and Toshiba as the 3 major players in the hard drive business across all product segments.
