What is disk stripping and disk mirroring?

Disk striping is the technique of spreading data over multiple disks. The data to be stored is divided into blocks and spread across several partitions on various hard disk. Disk striping is used with or without equivalence. Disk striping helps in improving the performance of the disk.

Disk mirroring is a process in which two duplicate disks are simultaneously created with the same data. This process is expensive, as it requires two disks to store the same kind of data. This process provides maximum security as if one disk fails the system switches to the other disk immediately to another disk without any data loss.
