1.2.4 Data Striping with Striped Parity (RAID 5)
The data is striped across disk drives. The parity data in a RAID 5 set is striped across all disk drives. RAID 5 is designed to handle small data blocks. This makes RAID 5 an excellent choice for multitasking, multi-user and database environments. The security provided by RAID 5 is that when one disk drive fails, all data is fully available, the missing data is recalculated from the data that is still available and the parity information. This data calculation can also be used to restore data to replaced defective disks.
