If you are going to build a RAID array from scratch, why use 0? If one disk fails, you lose everything. I would use RAID 5. It takes up more disks, but has built in redundancy. After all, RAID stands for Redundant Array of Independent Disks... what's a RAID without redundancy?
RAID 5 (striped disks with parity) combines three or more disks in a way that protects data against loss of any one disk; the storage capacity of the array is reduced by one disk.
RAID also stands for:
Rapid Array of Inexpensive Disks
Rapid Array of Indpendent Disks
Redundant Array of Inexpensive Disks
The acronym just means "the use of smaller drives to make a big one and/or one with more security."
In using software RAID for these devices, I'd recommend using RAID 0 (striped) for speed, but do keep in mind that if one drive fails the whole array will be lost, so dont store important information on these disks...keep a backup somewhere, and use the disks just for rendering and all that. Then back up the results somewhere safe(er) when you have time.
That's true, however, OS X does not support RAID 5 in software, so he'll have to get a separate enclosure that supports that RAID level. The best way to get redundancy and size in OS X is to concatenate two mirrored disks...losing half the available storage space to redundancy, but getting a larger disk than each independent one.
