I'm not sure, and maybe I'll repeat the test someday with that window 
open, although CM from VSL thinks I probably just have most of the 
data on the fast part of the drive.

In any case, I think that Firewire's bandwidth shouldn't be an issue, 
i.e. you'd probably get the same result with the drive mounted 
internally.

What could be an issue - and maybe I should have mentioned this - is 
that not all Firewire drives work 100% reliably in Pro Tools, so as a 
matter of course I move some of the tracks to the internal drive just 
to cut off any problems at the pass. You'll be going along fine, and 
then all of a sudden you'll get "disk too slow or fragmented" 
messages, when it's neither; moving tracks over is the only way to 
get it to be happy. I haven't experienced this with the EXS24 
streaming voices, but it could happen.
