RAID 0+1: This is a hybrid form of RAID that some manufacturers have IMPLEMENTED to try and give the advantages of each of the two versions combined. Typically this can only be done on a SYSTEM with a minimum of 4 hard drives. It then combines the methods of mirroring and striping to provide the performance and redundancy. The first set of drives will be active and have the data striped across them while the second set of drives will be a mirror of the data on the first two.

RAID 10 or 1+0: RAID 10 is effectively a similar version to RAID 0+1. Rather than striping data between the DISK sets and then mirroring them, the first two drives in the set are a MIRRORED together. The second two drives form another set of DISKS that is are mirror of one another but store striped data with the first pair. This is a form of nested RAID setup. Drives 1 and 2 are a RAID 1 mirror and drives 3 and 4 are also a mirror. These two sets are then setup as stripped array.
