The higher the number, the faster the rebuild will occur. However, if a higher number is selected, the system I/O rate may be slower. - Patrol Rate. Enter a number from 0 to 100 to control the rate at which patrol reads are performed. Patrol read is a preventive procedure that monitors physical disks to find and resolve potential problem that might cause a disk failure.
