Hi -- sorry to be so tardy in acknowedging your reply. I actually came across your post here when I was googling (again) for a solution to this problem.
By saving the result as html, there is some text there that says (in my case) that 8X writing is OK or not. This is the max rated speed of the media I'm using-- TYG02 . PTPXL 3.16 is ignoring the new Autostrategy write speed of 6X it's tested the media at -- so it doesn't appear to be doing anything other than lifting the speed from the media info. Not helpful.
BenQ Q-scan allows you to vary the speed of the write test, so that media that don't work at their max rated speed (8X) can qualify for good writes at 4X (typical). Can't do that here, and QScan doesn't work on Plextor drives.
This is pretty basic stuff, it seems to me -- examine/test the batch of media to see what speed qualifies for FE/TE in the given media-device-host configuration. A faster platform or a newer device will probably do better and support a higher write than a slow one. But without reliable FE/TE tests, it's pretty much a crap shoot. Read transfer rate tests are not adequate for this.
