I have a nice laptop I7 quad, 8 gigs of ram and just put a 250 gig ssd drive in it. What is the most effecient setup for recording? Currently i have a 500 gig external drive hooked up but i think its only 5400 rpm. Should i just find a 7200 rpm ext drive and call it a day? I am using the line 6 hd500x as my sound device currently and have no need to record live drums at the moment.
