RAIDExpress 133 RAID USER MANUAL
18
Setup Array for RAID 1:
The RAIDExpress 133 card allows two drives to be setup as a RAID 1 (mirror) array
or four drives as two arrays. The first mirrored array will be set as array 0 and the
second as array 1. RAID 1 is implemented as mirroring; a drive has its data
duplicated on the other different drive. Selecting RAID 1 can enhance read
performance and allow fault tolerance. RAID 1 array can thoroughly backup your files
to prevent data loss.
Note: Two hard drives that form a RAID 1 array have to be attached as the same
master or slave hard disks.
