In the illustration, volume 1 can be assigned a RAID level 5 of 

operation while volume 0 might be assigned a RAID level 1E of 

operation. Alterantively, the free space can be used to create vol-

ume 2, which could then be set to use RAID level 5.

RAID 0 and RAID 1 volume sets can be used immediately af-

ter creation because they do not create parity data. However, 

RAID 3, 5 and 6 volume sets must be initialized to generate 

parity information. In Backgorund Initialization, the initializa-

tion proceeds as a background task, and the volume set is fully 

accessible for system reads and writes. The operating system 

can instantly access the newly created arrays without requir-

ing a reboot and without waiting for initialization to complete. 

Furthermore, the volume set is protected against disk failures 

while initialing. If using Foreground Initialization, the initializa-

tion process must be completed before the volume set is ready 

for system accesses.

The SATA RAID controllers store RAID configuration information 

on the disk drives. The controller therefore protect the configu-

ration settings in the event of controller failure. Array roaming 

allows the administrators the ability to move a completele RAID 

set to another system without losing RAID configuration infor-
