DAE Tests

- Pressed and CDR AudioCD results

The NU drive supports 40x maximum reading speed for DAE media and uses CAV reading strategy. Nero CDSpeed confirmed these specifications.

To test the ripping speed of the drive, we ripped the contents of the same audio disc to our hard disk, using the CDDAE software. For CD-R media we used a clone of the pressed disc.

- Advanced DAE Quality

CDSpeed advanced DAE quality test awards the NU drive with a quality score of 100 (perfect) while for the same test, the LiteOn drive received only 50. On the other hand, the LiteOn proved to be about 5X faster than the NU in the ripping speed test. CDSpeed also confirmed that the NU Combo drive is able to read Subchanneel Data and Leadin informations but it does not support, as shown on the Advanced features tab, Leadout information.

- Support of 90/99mins AudioCDs

The NU ripped up to 81:24min of the tested 99mins AudioCD.

- Reading/Ripping Protected AudioCDs

For this test procedure, we used two audio discs with different audio protection schemes. We tested for both recognition and ripping to the hard disk. The software used was Exact Audio Copy.

* Pressed Audio disc protected by Sony Key2Audio (Celine Dion - New Day Has Come)

* Pressed Audio disc protected by Cactus Data Shield 200 (Natalie Imbruglia - White Lilies Island)

Both the NU and LiteOn drives, as the above table shows, have several problems with protected audio titles.
