We measured the C1 / C2 error rate on the recorded discs we burned at the various supported writing speeds and various media. The software we used is PleXTools Professional V2.24b, and particularly the built-in Q-Check utility. The reader was the Plextor PX-716A (firmware v1.08)

- Summary

The Asus reported good writing quality with most media while in a few cases, it needs some improvement. Especially in the case of Memorex and MMore media, Plextools reported C2 and CU errors. Writing at 16X or 32X is much safer than 48X or 52X and the above results confirm this.
