RAID levels are created to improve data redundancy and performance. IO's are run to test the performance of the RAID levels.

• RAID 0 - Striping, no redundancy

• RAID 1 - Mirroring, full redundancy

• RAID 5 - Striping with parity, good balance of performance and redundancy

• RAID 6 - Striping with double parity, better redundancy than RAID 5

• RAID 10 - Combination of RAID 0 and RAID 1, high performance and redundancy

• IO's are run to ...read more
