RAID is a technology that spreads your data across several disks, including redundant copies, so that if one disk fails everything will still work. That's a very simplistic explanation, but hopefully you get the gist.
 
If it's setup with anything other than RAID-0 (i.e. basically no RAID at all), it will almost certainly affect disk streaming performance.
 
You don't want RAID on your audio streaming disk.

scook : I have autosave turned off.

OK, here's where I'm at now.... I have eliminated firewire altogether. I bought a Focusrite Scarlett 18i20 (USB). Well, guess what.... I still have the same problems. So basically, at this point I have bought a new computer and a new interface just to try to get Cakewalk working properly for me. I'm getting pretty skeptical that I am ever going to get that. I'm totally out of ideas at this point. And, once again, through all of this, Studio One works perfectly. As much as I hate the idea, it's looking like I may have to bite the bullet and make the switch to Studio One. I mean, I've really tried here but, it just doesn't seem to be working out.
