Abstract:
A data storage device includes a cumulative data histogram of lengths of idle times between foreground user service requests. The cumulative data histogram is updated with measured lengths of current idle times between successive user service requests. Background service request are scheduled following a user service request after a time delay that is controlled as a function of the cumulative data histogram and a calculated length of a busy time of the background service request.
