Bryan, Actually, it's an interesting issue. I've looked just a little bit at this. I think it depends a lot on how you do it. RAID *can* improve raw throughput, but it *almost* *always* has longer latency, or at least the one's that I've set up. It has seemed that in audio work latency makes at least as big a difference as throughput, maybe more, and RAID didn't work well for me. Keep in mind that a 24-bit, 44.1KHz signal is only using a bit over 120KB/S, and my current EIDE hard drive under Linux is providing nearly 45MB/S, implying the ability to supply more than 200 stereo channels. (Assuming no seek issues, etc., which will happen.) However, I agree that if you have a good RAID controller that can do speculative look-ahead operations and has lots of caching on board the controller, it seems like it should help. Personally, I get 32 channels today from a single 1394 hard drive which suits my purposes very well. I haven't had the need to push further, but do this it would be interesting to try.
