- Compatible with LaCie 2big Thunderbolt™ 2
- Be ready in case of hard disk failure

Having a spare disk means that you're prepared in the case of a hard disk failure. Because disks are hot-swappable in RAID 1, you can immediately replace your failed disk with zero downtime. And for the ultimate in peace of mind and value, the LaCie 2big Spare Hard Disk features a three-year limited warranty.

Note that the capacity of your spare disk must be equal to or higher than the capacity of the disk being replaced.
