No, because the drive hardware needs to be tuned by the firmware to 
produce correct results. But looking at the output, you also support 6x 
writing in your drive. I would try writing this media at 6x, since it's 
a supported speed. That's about the upper end of how fast you write a CD 
at 48x, as a data point.

It may be that the firmware indicates it can operate at 8x, but can't, 
at least with this media.
