Hi,

as I am thinking of buying a DP Mac, i had a question about 
following. 

As I use the Mac only for music apps, I will have a lot of space left 
on the internal hard drive (120Gb). Is it wise to store my samples 
(mainly from libraries, which I hardly ever edit) on this drive? 

I'm also asking this because up to now I use 4.8 and from what I 
understand with vs. 5 it's possible to stream samples (so i guess 
this means heavier strength on the drive).

Thanks in advance,
Ewald
