Abstract
A method for copying data from a storage device that has been identified for replacement or has failed to a spare storage device. The method includes a storage controller tracking input/output statistics for several storage devices. The storage controller determines if a first storage device storing first data has been identified for replacement within the storage devices. In response to the first storage device having been identified for replacement, a first least written to data address space within the first storage device is determined based on the input/output statistics. First data contained in the first least written to data address space is copied from the first storage device to the spare storage device.
