Note: The process of rebuilding the data from parity from a failed drive is more impactful than performing a sick disk copy When should a drive be failed (rebuild) versus letting it fail gracefully (sick disk copy)?

Replaced disk model and character is similar to the failed disk. Replaced disk may show different type or RPM value from the original disk, example: RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks)
