The 1980s saw the minicomputer age plateau as PCs were introduced. Manufacturers such as IBM, DEC and Hewlett-Packard continued to manufacture 14-inch hard drive systems as industry demanded higher storage; one such drive is the 1980 2.52 GB IBM 3380. But it was clear that smaller Winchester storage systems were eclipsing large platter hard drives.
The phonograph cylinder is a storage medium. The phonograph may be considered a storage device especially as machines of this vintage were able to record on blank cylinders.

HDDs maintained this position into the modern era of servers and personal computers , though personal computing devices produced in large volume, like mobile phones and tablets , rely on ...
The IBM 1405 Disk Storage Unit was announced in 1961 and was designed for use with the IBM 1400 series, medium scale business computers. [25] The 1405 Model 1 has a storage capacity of 10 million alphanumeric characters (60,000,000 bits) on 25 disks. Model 2 has a storage capacity of 20 million alphanumeric characters (120,000,000 bits) on 50 ...
