The ideal raid level for uncompromised quality editing is RAID 10 (stripping with mirroring). Next economical solution for me is RAID 5, 50 (8 hdds needed), then 60. But you'll need a 3rd party RAID card & external drive bays. Apple's built in software raid 0 or 1 is OK but it's not hardware accelerated like w/ the ATTO HBA or other SATA RAID cards. I'm not sure if Apple RAID support raid 10. If it does, I'd use that. The minimum is 4 identical hdds. You can have two dead hdds w RAID 10 and it's still running (at half the speed). And there are vendor-specific RAID schemes that's somewhat proprietary. But they're optimized for video editing.

From the trend of the new smaller sized Mac Pro, putting four 4 Tb hdds in bay 1-4 and use the 2nd optical drive as the boot drive is probably the most economical solution with older silver colored Mac Pro. Eventually you'll have to get to the Thunderbolt bandwagon and that'll cost at least $5-10K for the new Thunderbolt enclosure. No thank you. I'll wait at least several years for price to come down and design to stabilize. I'm not doing heavy 4K now. Still 1080p. 8 Tb of RAID 1 via Apple software RAID will do 1080p workflow just fine for many years to come. I'm actually getting very fast performance when editing w/ AVC-I 100 and Pro Res 422 HQ 1080p w/ the Apple software RAID.
