On this configuration window, a "disk" refers to a physical disk drive, a "volume" refers to the
logical configuration of disk drives which may include multiple disk drives.
IMPORTANT:
If you remove a disk drive and insert it into a different drive bay, the system will consider it as a
new and different disk drive.
Some of the RAID levels provide data protection. Below is the summary of RAID level features:
