A single storage drive failure does not cause a data failure if you configured the storage drives as a mirrored RAID 1 volume (optional). The storage drive can be removed, and when a new storage drive is inserted, the contents are automatically rebuilt from the rest of the array with no need to reconfigure the RAID parameters. If you configured the replaced storage drive as a hot-spare, the new HDD is automatically configured as a new hot-spare.
