Just a little something.  Fast is nice and good, BUT.  You do not have to have all the fastest drives like everyone thinks.  Before you slam me they are nice, yes.  But I started 3 years ago capturing with a 33, 5400 drive and it worked just fine.  It matters just as much to have as little running in the background.  Yes, now I have a much larger and faster machine, but that just makes things go smoother.
