Disk mirroring is a protocol in which data is copied to two or more disks in tandem to prevent the risk of data loss due to hard drive anomalies. Duplicate data stored in more than couple of identical hard drives are connected to a disk controller card that can make it highly and easily available. With disk mirroring paradigm, you can be rest assures of complete data retrieval even in the failure of a hard drive. This is because data replication to two or more hard drives allows you access data from a hard drive that is serviceable.
