The present disclosure provides a system that includes an array of disk drives and a controller communicatively coupled to the array of disk drives. The controller is to identify, within the array of disk drives, a predictive failed disk. The controller also rebuilds data of the predictive failed disk on a spare drive in a regeneration mode and determines a regeneration time baseline. The controller also rebuilds data of the predictive failed disk on the spare drive in a copy mode and determines the copy mode execution time. The controller switches to regeneration mode if the copy mode execution time is greater than the regeneration time baseline. |
