Check out my BenQ DW1620A review here: http://www.cdfreaks.com/article/159
A personal thank to BenQ for being very helpful and actually fixing the problems I’ve reported - unlike most other companies I’ve had contact with.
I did check my review against the review at CDRLabs as I’ve found their reviews to be trustworthy too unlike a lot of other reviews I’ve seen: http://www.cdrlabs.com/reviews/index.php?reviewid=245
And I do notice that some test results are not identical. My drive do never have any problems writing DVD-R at 16x for example. I did also notice that the writing times posted over at CDRlabs was 10-15 seconds higher than what I got with my drive.
You may also request additional tests in this thread if you want.
