I plan to increase my external/scratch disk storage, and am looking at going with a hardware RAID. I currently have a single 500GB drive for my scratch disk, but find that I keep hitting the limit on that when I have more than one project going at a time. Fry's currently has Maxtor 500GBPATA and Seagate 500GB SATA drives for $109 each, so I figurred I'd pick up 2 or three. My question is, would I be better off going with a 2 drive RAID 0, or a 3 drive RAID 5? Both will give me 1TB available storage, but the RAID 5 has parity (redundancy) where as the RAID 0 does not. But I hear that the RAID 0 offers better performance, because it doesn't have to write the parity bits on each record operation. I don't know what the real world performance difference between the two is though, and if it's below the threshold of FW800, I guess it would be moot. So just looking for comments from those of you that have hardware RAID storage systems, what your thoughts/preferences are.
