DVD+R DL/-R DL Writing performance
DVD+R/-R Double Layer writing performance and quality:
The Lite-On iHAS324 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 8x.
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 disc’s quality; we then finally ran a read-back test on our Optiarc AD-7201S using Nero CD-Speed.
