That sounds perfectly reasonable. I had been concerned that the i4 wouldn't even talk to the drives, given that they're rated faster than its top speed, but if it's just an issue of *possibly* sacrificing a bit of speed (which, given your explanation, seems unlikely anyway), then my problem is solved. Thanks! :-) BTW, if anyone is interested in hearing how this information performs (either from a developer's or a user's perspective), shoot me an e-mail in a couple of weeks, when I've had a chance to get everything installed properly.
