Rapid rebuild

Smart Array controllers include rapid rebuild technology for accelerating the rebuild process. Faster rebuild time helps restore logical drives to full fault tolerance before a subsequent drive failure can occur, reducing the risk of data loss.

Generally, a rebuild operation requires approximately 15 to 30 seconds per gigabyte for RAID 5 or RAID 6. Actual rebuild time depends on several factors, including the amount of I/O activity occurring during the rebuild operation, the number of disk drives in the logical drive, the rebuild priority setting, and the disk drive performance.

This feature is available for all RAID levels except RAID 0.
