Simple Volume; Spanned Volume - Adaptec RAID 21610SA Installation And User Manual

RAID 10
This dual-level RAID type is created by using two or more equal-
sized RAID 1 arrays to create a RAID 0. Both read and write
performance are improved due to array striping. However, the
performance improvement costs additional storage space due to
the mirroring of the arrays.

Simple Volume

A simple volume consists of a single disk drive.

Spanned Volume

A spanned volume is created by joining, or concatenating, two or
more disk drives. The drives do not have to be of equal capacity
and are connected end-to-end. A spanned volume offers no
redundancy and no performance advantage over a single drive.
