About RAID

A RAID (Redundant Array of Independent Disks) provides better
performance and reliability from combinations of drives than is
possible with the same total storage space without RAID.
This Appendix describes the various RAID levels supported by
Adaptec RAID controllers.
The table below shows the number of drives needed and
supported for your controller according to RAID level.
Array
Type 2410SA
RAID 0 4 / 2
RAID 1 2 / 2
RAID 5 4 / 3
RAID 10 4 / 4
RAID 50 N/A
Note: Select RAID drives of equal capacity and performance.
Otherwise, the RAID tends to be limited in capacity and
performance to that of the smallest and slowest drive.

Simple Volume

A simple volume consists of a single drive.
