The 1.5TB 4big Quadra and 5big Network Spare Drive from LaCie is a spare drive for the 4big Quadra and 5big Network series of arrays. The drive is ready to be installed in your 4big or 5big in the event of the failure of any one of its physical hard drives. Simply remove the bad drive and slide the replacement drive in. Having a spare drive on hand minimizes the downtime associated with a drive failure, allowing your RAID protected array to start rebuilding lost data immediately.
