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. As of March 2012 independent manufacturers were Seagate, Toshiba and Western Digital.

  • 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. As of March 2012 independent manufacturers were Seagate, Simmtronics, Toshiba and Western Digital. The following is a list of notable defunct HDD manufacturers: Alps Electric – left industry Amcodyne Ampex Apple, Inc.  – produced the proprietary Lisa 20MB Widget drive in house in 1984 for less than two years before leaving the hard drive business.

  • В общей сложности насчитывалось более 200 компаний, когда-либо производивших жесткие диски. Большая часть из них прекратила свое существование, была куплена другими производителями или перепрофилировалась на выпуск другой продукции. На 2011 год осталось всего три производителя — Seagate, Western Digital и Toshiba. Вот список некоторых компаний, занимавшихся выпуском жестких дисков: Apple, Inc.  — выпускала с 1984 г. проприетарный жесткий диск Lisa ёмкостью 20MB. Atasi Corp.  — банкрот.
  • 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. As of March 2012 independent manufacturers were Seagate, Toshiba and Western Digital.
