Creating a Separate High Performance Data Volume

As in the previous two examples, we’ll assume that you’ve purchased a computer with
a RAID card and four 500 GB disk drives. In this example, you want to take advantage of
RAID to create a fast data volume (for video editing, perhaps) and aren’t worried about
data protection. You’ll leave the current startup disk as is, and use a RAID 0 scheme to
create a separate volume on the remaining disks. RAID 0, which stripes data across the
drives in the RAID set, usually offers the highest performance. However, neither the
startup disk nor the data volume benefit from any data protection.

To set up this example:
First, because we’re leaving the original startup disk untouched, there’s no need to
restart the computer from a different disc; just open RAID Utility and use the Create
RAID Set command to create a RAID 0 set using the three remaining disks. When the
RAID set appears in the list on the left side of the RAID Utility window, select it and use
the Create Volume command to create the volume. The result is a fast 1,500 GB data
volume that is independent of the computer’s startup disk.
