Even tho the listed power for the hub was ample for an external hard drive. Don't know what's going on there.
Don't want to burn anything out.
Mechanical HDDs can draw several times their normal (steady-state) power when the platters first spin up. That would be my guess as to the reasoning behind the warning. If the drive has its own power brick it ought to be fine.
How's the power draw profile from DVD drives compared to HDDs?

I would say assuming the power issue is settled with each DVD drive having their own power supply, then I wouldn't worry too much about data rates. You should still be getting a gain reading in parallel. The shared bandwidth should in theory just roundrobined across all drives. But that also begs the question: since this is a one time thing and you value data accuracy more, why in such a hurry? Just do it right and steady once and be done with it?
The Model M is not for the faint of heart. You either like them or hate them.
