DAE Tests

- Pressed and CDR AudioCD results

The BTC uses 42x CAV reading strategy for CD-DA. Below you can see the results from the CDSpeed transfer rate test with a pressed audio CD:

According to Nero CDSpeed, the average reading speed was 32.08x, while at the end of the reading process it reached a maximum speed of 42.38x. The seek times are also good.

We ripped the contents of the same audio disc to our hard disk, using the CDDAE software. The average ripping speed (burst mode) of 30x, is high.

The same pressed audio disc was copied onto a CD-R and was read again with CDspeed.

- Advanced DAE Quality

In the Nero CD Speed Advanced DAE test, the BTC drive returned an average speed of 23.25x, which is good performance, and a quality score of 99.9. According to CDSpeed the drive can read Cd Text and Subchannel Data but this is not the case for Leadin and Leadout.

- Support of 90/99mins AudioCDs

The BTC drive managed to playback a full 90min audio CD without problems, but didn`t managed to play the 99min test discs, having reading problems with all tracks.

- Reading/Ripping Protected AudioCDs

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

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

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

The BTC drive played back successfully only the Key2AudioCD but failed with the Cactus Shield Audio protected disc.

*Download firmware vB028 which fixed the problem
