Organize the physical disk drives in arrays after the drives are con-
nected to MegaRAID IDE. Each array can consist of one to two 
physical disk drives.

The most important factors in RAID array configuration are drive 
availability (fault tolerance), and drive performance. 

You can maximize the drive availability by increasing fault toler-
ance. Use RAID 1 or mirror configuration to attain this objective.

Maximizing Drive Performance 

You can optimize drive performance by using striping. Select 
RAID 0 or striping to configure an array for optimal performance.

Only one RAID level can be assigned to each array. The drives 
required per RAID level is:
