List of manufacturers[edit]

Diagram of consolidation

It has been estimated that over 200 companies were hard disk drive manufacturers at one time or another. Besides competing on features such as hard disk (HDD) data density and latencies, many of those companies started to support new, smaller form factors that enabled the ever-reducing physical sizes of computing devices. Most of that industry has vanished through bankruptcy and acquisition. Surviving manufacturers are Seagate, Toshiba and Western Digital.

The following is a list of known defunct HDD manufacturers:

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.

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."
