ABSTRACT:
The present invention measures the usage level of removable media devices using residency time. In one embodiment, a usage level measurement software facility receives a number of data storage medium access requests. For reach received request, the facility performs a number of steps. The facility first assigns the request to a particular one of the removable media devices. Then, under the control of the assigned removable media device, the data storage medium access request is performed. For each performed request, the facility records a residency time. The residency time reflects the amount of time taken by the assigned removable media device to perform the request. The facility aggregates the recorded residency times to produce a measure of the collective usage level of the plurality of removable media devices.
