Category:Rotating disc computer storage media

From Wikipedia, the free encyclopedia

This category revolves around various types of rotating disc computer storage media. The discs may be permanently attached to, or removable from, the computer. For large computer systems such as mainframes and server farms, the discs may be connected to a network, and thus may be situated physically distant from the computers they serve. In the latter setup, rotating discs tends to replace some magnetic tape data storage systems (although tape storage is still less expensive per data unit stored).
