DVD+R DL/-R DL Writing performance
DVD+R/-R Double Layer writing performance and quality:
The Optiarc AD-7200A supports the DVD+R DL/-R DL standard for writing Double Layer/Dual Layer discs with a size around 8.5 GB at a writing speed of 12x. Unfortunately, we didn’t have any media that was supported at this speed.
DVD+R DL:
For these tests we wrote an image file of a DVD-Video compilation of as near full capacity as possible with CD-Speed. We then used the Lite-On along with CD-Speed to test the discs quality; we then finally ran a read-back test on our Optiarc AD-7200A using Nero CD-Speed.
Reviewers Note:
The Lite-On LH-20A1L is not able to perform a jitter test on the second layer of a DL disc. We therefore omitted the jitter test in our DL media tests.

Considering our 2.4x media was written at 4x, the result is good.
