It is the act of splitting data and storing it randomly.

Detailed explanation-1: -RAID 5 is disk striping with parity. With this level of RAID, data is striped across three or more disks, with parity information stored across multiple disks. Parity is a calculated value that’s used to restore data from the other drives if one of the drives in the set fails.
Detailed explanation-2: -A RAID 5 array is built from a minimum of three disk drives, and uses data striping and parity data to provide redundancy.
Detailed explanation-3: -Raid 6: Striping with Double Parity This setup requires a minimum of four drives. The setup resembles RAID 5 but includes two additional parity blocks distributed across the disk. Therefore, it uses block-level striping to distribute the data across the array and stores two parity blocks for each data block.
