Thank you for the nice review.
I’ve found some quirk that you might be interested in checking further:
As to it’s manual, this drive does CD-R writing at speeds of 4, 8, 16, 24, 32 and 40x. Now Discspeed confirms this (see first screenshot below and let’s me choose all speeds. So doing a simulated create disc selecting 16x speed leads to a 16x CLV writing curve.
However ImgBurn only allows speeds 24, 32 and 40x (see second screenshot). So does Nero (7).
PS: This is true for any sort if dye (Cyanine, AZO or Phthalocyanine), so it’s not some kind of ATIP-style limit.
