Abstract
A method, computer program product, and computer system are provided for testing drives in a redundant array of independent disks (RAID) array. The method includes: mirroring data from a selected drive to be tested in a RAID array to spare storage space in the RAID array; and, once the data is successfully mirrored, testing the selected drive to identify a preemptive failure of the selected drive. The RAID may be a traditional RAID (TRAID) array and the spare space may be a spare physical drive independent of array drive members. The RAID array may alternatively be a distributed RAID (DRAID) array and the spare space may be spare capacity spread through the array drive members.
