8 Under Options, choose whether you want to use space from the additional drives to

expand the existing volume or leave the extra space free for creating other volumes

later.

Expand volume using added capacity: Expands the original startup volume to use all

available space on the new RAID set.

If you don’t select this option, RAID Utility retains the original startup volume on the

new RAID set and leaves the remaining space on the RAID set free for you to create

other volumes when you want.

9 Click Migrate.

10 When the migration process is nished, quit RAID Utility.

11 Quit the Installer and restart the computer.

Creating a RAID Set

Before you can create a RAID volume, you need to combine physical drives into a

logical disk called a RAID set.

The number of drives needed to create a RAID set depends on the RAID level you want

to use. You can use a single drive to create an Enhanced JBOD set, two drives to create

a RAID 0 or RAID 1 set, three or four drives to create a RAID 0 or RAID 5 set, or four

drives to create a RAID 0+1 set.
