Introduction to RAID

RAID (Redundant Array of Independent Disks) allows multiple hard drives to be 
combined together in a disk array. Then all or a portion of the disk array is formed 
into a logical drive. The operating system sees the logical drive as a single 
storage device, and treats it as such. The RAID software and/or controller handle 
all of the individual drives on its own. The benefits of a RAID can include: 

•

Higher data transfer rates for increased server performance 

•

Increased overall storage capacity for a single drive designation (such as, C, 
D, E, etc.)

•

Data redundancy/fault tolerance for ensuring continuous system operation in 
the event of a hard drive failure

Different types of disk arrays use different organizational models and have 
varying benefits. Also see Choosing RAID Level on page 247. The following 
outline breaks down the properties for each type of RAID disk array:
