The common wisdom is to burn at 1 or 2 speeds lower than the maximum
rating of the media. The USB2 host speed is really not such a big issue
here; the buffer underrun protection of the DVD burner will kick in if
data throughput is too slow at any given time.

Yes, DVD is very different; this is but one way but it is one that has
real impact on practical utilization.

Agree. The flexibility of an external burner than can be used on other, or
future machines, is a big plus. Adding hardware to an old machine just
doesn't make sense if there are alternatives.
