This article applies to Mac OS X 10.4 or later and Disk Utility version 10.5 or later (included with Mac OS X 10.4 Tiger).
RAID sets can be combined in a variety of ways to increase their usefulness. For example, you can create a RAID 10 set by combining a mirrored RAID and a striped RAID. This would allow you to combine the fast disk access of a striped RAID set (RAID 0) with the data protection features of a mirrored RAID set (RAID 1).
To combine RAID sets:
- Create three blank RAID schemes in Disk Utility (two mirror and one stripe, or two stripe and one mirror).
- Drag two of the drives to the first set.
- Drag the other two drives to the second set.
- Then in the RAID window drag the first and second set into the third scheme.
- Click Create.
