Kinda depends on the burner speed. This is a math question more than an expert preference question. An 8X burner can do a disc in 10-15 minutes. So that running unattended overnight would probably do well for these sort of runs. I’d check with the makers, I’m sure there’s a model that gives you the speed and capacity you’re looking for. Again, I’m a huge fan of fully unattended burning.
