Setup Array for RAID 0+1:
A RAID 0+1 (mirror and stripe) array has to be formed by four hard drives. RAID 0+1
is implemented as a mirrored array whose segments are RAID 0 arrays so RAID 0+1
also has fault-tolerance capacity as RAID 1. It not only enhances hard disk access
performance but also backups data to prevent data loss. The formed array is
automatically set as array 0.

RAIDExpress 133 RAID USER MANUAL

Setup Array for JBOD:
The RAIDExpress 133 card allows you to use two, three or four hard drives to form a
JBOD (Just a Bunch Of Disks) array as array 0. Although JBOD doesn ’t offer other
RAID functionality, it makes the hard disks appear to be a single one by combining
the drives into one larger logical one without any capacity loss.
Setup Array for Normal:
You can use the RAIDExpress 133 card as a normal IDE controller. The
RAIDExpress 133 card allows you to use one, two, three or four hard drives. All the
hard drives attached on the RAIDExpress 133 controller are left to act as
independent drive volumes.
