Xbox Backups

I want to make backups of all my xbox games. I already installed a mod chip, now I need to get a dvd rw. I have read a lot of people use and like the Pioneer A06. I have also read that the A06 is the same as the 106 model. So I had a few questions. What is the diffrence between the 106BK and the 106D. Just the color? And what is the diffrence between the A06USPK4 and the 106BK and the 106D? Which one would be the best for backing up xbox games? I have a thompson drive in my xbox, Im not sure if that makes a diffrence or not.
Thanks
