Looks to me like he'd need three 20X writers on the same USB
controller before he'd have problems. He could (theoretically) solve
this by slapping in an extra USB controller and putting one of the
writers on it, though when you have three DVD burners in a machine,
I'd suspect (but am too lazy to actually look up sustained transfer
rates and calculate the effects of repositioning the heads to read
three or more image files simultaneously) that reading data from the
hard drive fast enough might then become the bottleneck. If you have
enough RAM, you could read the images in from the hard drive into
memory, then spew them out to the burners.
