Does the Read/Write Quality of a CD Burner Go Down After Too Much Use?

[mikeniceusa]

I have ripped and burned thousands of CDs and DVDs (5000+) using my little Lite-On Super AllWrite burner. It still seems to rip & write great, but I am wondering if should replace it any way? Does the quality of the reading and/or writing go down after so much use? I don't have time to listen...
