Depending on the type of RAID you choose for your array, RAID can provide higher capacity, performance, and reliability from your storage devices. Supported RAID levels are identified in the table below. Be sure to check your controller documentation to confirm which RAID types your controller supports.

In addition, Adaptec Storage Manager supports the following:
A simple volume consists of a single disk drive.
A spanned volume is created by joining two or more disk drives. The drives do not have to be of equal capacity and they are connected end-to-end. A spanned volume offers no redundancy and no performance advantage over a single drive.
A RAID volume is created by joining two or more single-level arrays of the same RAID type. Unlike dual-level arrays, the arrays in a RAID volume do not have to be of equal capacity. In direct contrast to dual-level arrays, the second-level arrays in a RAID volume are not striped together, instead they are connected end-to-end.
