Burning/reading the 32x CD-RW disc at 24x speed:

There were no problems during the burning/reading of the discs. The graphs are similar to what we have seen with the 24x CD-RW, so let’s get right to the quality check.

 
 
Quality of the 32x CD-RW disc burning at 24x speed:

The distribution of errors on the two discs is similar: there’s a peak of C1 errors at the beginning of the medium. This peak quite suddenly goes down as the drive achieves its maximum burn speed. The new model, however, has a much better total of C1 errors. The asymmetry on the disc written by the GSA-4163 is still very close to zero, and the jitter rate is lower and more uniform than on the disc burned by the previous model. The GSA-4163 gave out a good disc, considering it doesn’t officially support 32x burn speed for CD-RWs.

Thus, the new model is better than the older one with rewritable CD media, too. The manufacturer has managed to improve the good performance of the GSA-4160, and the new GSA-4163 delivers excellent quality with all the tested media.
