Hello, I'm in the market for an External DVD burner or Superdrive for my MBP. In this regard, I'm looking at the familiar USB vs FW800 problem. (I installed MCE Optibay in my superdrive slot, and would like a purpose built external optical drive, rather than the superdrive-in-enclosure approach) For external Hard Drvies, I favor FW800 to the extent possible, due to its higher sustained transfer speeds. Is this still a valid consideration for Superdrives? Or is the speed of the drive the limiting factor there? The fact is that USB gives me a lot more options in terms of sizes and price. But if performance is an issue, I'd rather go for FW800. I'm not that knowledgable in this regard, so I could use some guidance (both read/write speeds for DVDs/DL-DVDs) Any help will be appreciated!!
