********************************** Drive Usage Per Hour ********************************
*
* The drive usage is given by the amount of time a drive is used for either
* writing or for reading purposes. These details can be obtained from the
* MMDriveHistory table. The time at which a write or a read operation has
* started is given by TimeStart column. Hence we can obtain the amount of time
* a drive is in use by summing up the DataWriteDurationSec+DataReadDurationSec
* grouping by the DriveId. Using the above sum we can find the percentage of
* time the drive is in use over one hour and twenty four hours duration.
*
****************************************************************************************
************************* Throughput of the Drive in GB/Hr *****************************
*
* The throughput of a drive is calculated based on the amount of data has been
* read or written to a drive in an hour. The columns DataWritten and DataRead in
* the same table as above gives the required data. This sum DataWritten+DataRead
* is again averaged for the last one hour and for twenty four hours.
