LaCie offers spare disks as a
convenient option to further protect your data. Because they are
hot-swappable, you can immediately replace your failed disk in case
of a problem and a secured RAID mode will automatically rebuild,
without any downtime in your workflow. In order to work properly,
the capacity of your spare disk must be equal to or higher than the
capacity of the disk being replaced.
