A tale of two busses

[unixronin]

Or rather, a question.  I was recently observing the availability of SATA DVD writers, and the question occurred to me:  Is there any actual advantage to an SATA DVD drive over a PATA one, other than just eliminating PATA devices?  Does a DVD writer actually transfer enough data to make the higher bandwidth significant?  If you have an existing PATA DVD writer, is there any compelling technical reason to replace it with an SATA one?

Inquiring minds want to know.

I don't think there's any DVD writer out there that requires that at the moment. Even my 12x Plextor burner is only UDMA33. You could hit 30x before you'd need the power of SATA.

That's what I was thinking. The only benefit I can think of, really, is "eliminate PATA". Though possibly a Blu-Ray drive might approach the limit .... I have a 16x DVD writer, iirc, and Blu-Ray gives four times the data density (again iirc).
