Rebuilding Times

Rebuilding a protected RAID array takes many hours, depending on the capacity of the disks and your NAS'
available resources (concurrent tasks such as backups or torrent downloads will slow rebuilding). Changing to
an unprotected RAID mode (ie RAID0) takes less than a minute. Note that data is accessible during rebuilding.

ABOUT RAID MODES

Refer to the table below for an overview of the different RAID modes, and see the descriptions for details. Note
that this information is also explained in the RAID Setup Wizard on the Dashboard (see above for details).
