Data blocks are striped across the disks, and on one disk a parity checksum of all the block data is written. The parity data is not written on a fixed drive but is spread across all the drives. With this data, the computer can recalculate the data of other blocks. That means this type of array can withstand the failure of a drive without losing data. Although it can be achieved in the software, it is recommended to use a hardware controller. The extra cache memory is used on these controllers to improve the write performance.
