RAID MODES

A Redundant Array of Independent Disks (RAID) is a system that utilizes multiple
hard drives to share or replicate data among the disks. The benefit, depending
on the selected RAID Mode (combinations of disks), is one or more of increased
data integrity, fault-tolerance, throughput or capacity when compared to single
drives.
Deleting the current partition prior to changing RAID modes is highly
recommended.
Using identical HDDs with the same capacity and RPM, and from the same
manufacturer are highly recommended for best capacity utilization.
