[QUOTE=corso;2768401]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 [B]Imgburn [/B]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 [B]Nero cd-dvd speed[/B] 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?
Welcome to the forums, corso!
I did some burns with this drive using a very good CD (JVC = Taiyo Yuden), as shown above. 16x is the slowest speed this drive burns this particular disc at; you won’t achieve a slower write speed in ImgBurn by specifying a slower speed, since the writing speeds are controlled by the firmware. The results look pretty good at 16x and 24x, although jitter is a tad high. Above 24x jitter seems too high to me. If you’re using a lesser quality CD, your results won’t likely be as good as the ones above. In summary, you should be ok burning at 16x or 24x with good quality CDs, as long as you let the laser cool down (~15 minutes) between burns.
There are numerous tutorials around the forums on using CD-DVD Speed for scanning discs. If you’re interested, check out the Disc Testing & Methods forum.
