Replace your failed disk with no down time!
The LaCie 4big Quadra Spare Drive conveniently stores and protects your digital data. Because it is hot-swappable, you can immediately replace your failed disk in case of a problem. The 4big drive's 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.)
