LaCie 4TB 4Big Quadra Spare Hard Drive

The LaCie 4TB 4Big Spare Hard Drive 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.
