I've just purchased a Plextor PX-891SAF. I must burn many audio CDs. Which speed is the best? I need to prevent the degradation over time. Theoretically, the lower speed the better, but in the specifications that Imgburn shows, apparently the lowest speed is 16x. Is it possible to burn at slower speeds just selecting them manually? Is it worth?
If tests must be done to determine the optimum speed, how? I see in this thread that Nero cd-dvd speed is used to make dvd tests, but I don't know how to start or how to understand the graphics. Does anyone know a tutorial for this?
Besides the speed is there anything else I should consider?
