Sony DRU-800A

9. C1 / C2 Error Measurements

We measured the C1 / C2 error rate on the recorded discs we burned at the maximum supported writing speed of 48X. The software we used is PleXTools Professional v2.23, and more specifically the built-in Q-Check utility. The reader was the Plextor PX-716A (firmware v1.06).

BenQ 80min 52X @ 48X

Intenso 80min 52X CD-R @ 48X

Ridisc 80min 52X @ 48X

Traxdata (black dye) 80min 40X @ 40X

Traxdata 80min 52X @ 48X

Verbatim 80min 52X @ 40X

- Summary

The CD writing quality, according to Plextools, is very dependent on the inserted media. With BenQ and Ridisc media, the Sony drive needs a lot of improvement. With Traxdata media however, even at 48X, with the current firmware the quality seems to be simply great.
