10.4: How to create a partitioned RAID setup
Authored by: Numbski on Jun 22, '06 10:24:57AM

Seems to me that it would make more sense to just create a single raid array, then partition the newly formed disk:

Use RAID5 (striped) on the three disks. Creating a new virtual disk. Now partition that virtual disk into 3 volumes as you see fit. You'll get more redundancy that way too.

Now if you have two disks and want three volumes, do a mirror set, then partition that one mirror set to 3 volumes. What you're doing is asking for trouble later.

SATA?

Does this work with SATA I tried to partition a mirrored RAID and was unable.
The RAID option tab did not show up in Disk Utility.

10.4: How to create a partitioned RAID setup
Authored by: beauh on Jun 22, '06 03:52:59PM

Not quite... RAID 5 isn't possible through software (apple's at least), nor is slicing an array. The OG post is the only way to end up with multiple partitions + RAID.
