Each provides disk fault-tolerance (except RAID 0) and each represents trade-offs depending on the characterization of the application workload. When combining RAID 0 and RAID 1 (sometimes called RAID 10), we actually have seven variants of RAID arrays. There are six main types of RAID array architectures: RAID-0 through RAID-5. Sophisticated algorithms are used to code and decode parity. Parity is quite small in size compared to the actual data but can be used to re-create the original data should it be destroyed as a result of a disk failure. ![]() RAID parity is a means of duplicating data by emulating it through parity information.
