I recently bought a 40x12x48 cdrw. However, I discovered that for $15.00 more I could have bought a 48x12x48. My question is, what is exactly the time difference between these two? If you could record a cd in 10 minutes with the one I have, how much time would it take for the one that’s a bit faster? Is it worth me taking the one I have back for the faster one? Any advice would be most appreciated. Thanks.

The one I have is a Digital Research. The one that I am thinking about swapping it for is a Memorex.
