It's just the 80GB internal drive that comes with the Mac 
(partitioned into 6GB + all the rest). But I'm not sure those voices 
are all streaming - in fact I suspect they're all playing from memory.

I'm not serving a point, I'm just putting samples in the most 
convenient place. It's hard to think of anything else useful for that 
much storage space!

Nobody talks about the other limit, which is 64 voices per EXS24. 
That will come into play very quickly with the new streaming 
libraries. People are filling up all 160 Gigastudio voices with one 
complicated program. Remember, an 8-layer crossfaded program uses 
eight channels for each voice.
