Physical Disk\Disk Transfers/sec

The Disk Transfers/sec is the number I/O request Packets (IRP) that has been completed during the sampling interval. A disk can only handle one I/O operation at a time. So the number of physical disks attached to the computer serves as an upper bound on the sustainable disk IO rate. Where disk arrays are used, divide the Disk Transfers/sec by the number of disks in the array to estimate individual disk I/O rates.

The Physical Disk(n)\Average Disk Service Time/Transfer can be calculated by taking the Physical Disk(n)\Disk Utilization and dividing it by the Physical Disk(n)\Disk Transfers/sec for each physical disk. This indicates how fast the drive responds to a request. If this climbs above what is specified ...
