15089: Acronis Disk Director 11 Advanced Server: Repairing RAID 5 Column

Last update: Sat, 2016-04-02 21:52

When a member of a RAID 5 volume fails, the operating system directs the reading and writing all of new data to the remaining members of the volume. A single member failure will not result in data loss, but reduces overall performance of a RAID 5 volume. Repairing a RAID 5 volume restores its performance by reconstructing the data of the failed member on another disk.
