[Avid-L2] 2 way vs. 3 way stripe internal raid on MacPro?

 

We've been running a two drive internal stripe on a MacPro OS 10.5 something SNDX 4.0.5 and doing pretty well  with DNX 220,220X.  I do get occasional stalls and dropped frames on output and sometimes it's very problematic punching in fixes but it is livable.  I'm thinking of try a 3 way stripe in the future.  In theory that should have better throughput, right?  Just curious if there is anything about an odd number of drives in a stripe that could be problematic.  I know RAM needs to be in matched pairs but I wouldn't think that has anything to do with a striped set of drive.  Of course adding a 3rd drive would increase the potential for failure but that's not a deal breaker.  Curious what more storage savvy folks think.  Maxing out the MacPro with a system and 3 storage drives will increase the tub heat but is that any cause for concern?
