RAID Arrays

NVRAID supports the following types of RAID arrays described in this section: RAID 0: RAID 0 defines a disk striping scheme that improves the disk read and write times for many applications.

RAID 1: RAID 1 defines techniques for mirroring data.

RAID 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1 arrays.

RAID 5: RAID 5 defines techniques for parity data.

Spanning (JBOD): JBOD provides a method for combining drives of different sizes into one large disk
