0 = Disk striping for performance
1 = Disk mirroring with slight performance improvement
2 = Hamming encoding. Encode data on disk with error correcting code. Data on a single disk is correctable when error occurs
3 = Virtual disk blocks. Data is striped across multiple disks with a single disk for parity information. Data can be reconstructed based on parity.
4 = Dedicated parity disk. Parity of all data is stored on a separate disk. Data can be reconstructed based on parity
5 = Striped parity disk. Parity is striped across all disks.
