The Storage Info frame in the device performance page displays the monitored storage volumes (logical disks or partitions), their names, sizes and current usage. For devices polled through WMI or VMware web service, disk latency and IOPS (input/output operations per second) parameters are also shown.
One can configure which of the storage volumes of the given device will be monitored in the Edit Device page, Storage tab.
