DAE Tests

- Pressed and CDR AudioCD results

The Optorite DD0401 uses the 40x CAV strategy for CD-DA. Below can be seen the CDSpeed transfer rate test with a pressed audio CD:

According to CDSpeed, the average reading speed with this disc was 30.52x, while the reported seek times were satisfactory.

We ripped the contents of the same audio disc to the hard disk with CDDAE software. The drive gave an average ripping speed (burst mode) of 28.5x:

In the same test, the Philips and Plextor drives were only slightly faster giving average speeds of 29.4x and 29x respectively.

The same pressed audio disc was copied onto CD-R media and was read again with CDspeed. Philips DVDR824P gave the highest ripping speed again, finishing the task at 29.8x average.

- Advanced DAE Quality

In the Nero CD Speed Advanced DAE test, the Optorite drive logged a perfect 100 in the quality score, with an average speed of 28.67. This is marginally slower than the speeds returned by both of the other drives.

- Support of 99mins AudioCDs

Ripped up to the 87th minute.

- Reading/Ripping Protected AudioCDs

For this test procedure two audio discs with different audio protections were used. The tasks tested were 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)

In the read/rip protected audio CDs test, the drive managed to rip both the Key2Audio and the CDS200 audio protected discs, but presented problems with the first track. The first track could not be ripped.
