Correct.
And given the fact that NewMedia rated the Conner 2107s (2gig) and 4207s (4 gig) 
drives as being the top performers for video in their issue around 2 months ago, 
what does that do to the exclusively_micropolis theory?  I've been using the 
4207s for around 9 months (serial #s 001 and 002) and get reliable sustained 
throughput in excess of 6 megs/sec. with 16bit 44.1KHz audio - and no t-cal.
