scratch disk
A hard disk used to store data temporarily. In highly computational applications such as editing large images or video, the scratch disk is used to hold the data being edited. If there is only one drive in the system, a separate partition can be created and not used for anything else, ensuring there is always available space. However, having a separate drive for the scratch disk improves performance. For professional use, one or more separate high-speed drives may be designated as scratch drives. See scratch tape and scratchpad.
