A testing for this feature has been done, and the results are shown as following.

Testing Methodology
In order to show the real writing speed for each media, CD-DVD Speed will be used for such testing. The PI, PO & Jitter values of each burnt media will also be measured by it after real writing. It aims to show the writing quality under 12x or 16x writing speed. There are 10 brands DVD+R media (see list below) will be tested, and which are supported to write as 12x or 16x speed by BenQ DW1600 DVD Re-Writer.

Conclusion
The drive performance is always an important point for end users, but the writing quality is the most consideration factor for R & D Engineers. It is the major target to achieving both performance and quality in BenQ Optical Storage Products.

BenQ believes that the over-speed burning feature must bring a great benefit to customers. And, more 8x DVD+R media will be supported for this over-speed burning feature by later firmware version.
