DAE Tests

- Pressed and CDR AudioCD results

The BTC DRW1008IM uses 32x CAV strategy for CD-DA. Below is the resultant output from the CDSpeed transfer rate test with a pressed audio CD:

According to CDSpeed, the average reading speed with this disc was 32.36x, while the reported seek times were rather good.

We ripped the contents of the same audio disc to our hard disk, using the CDDAE software. The test returned an average ripping speed (burst mode) of 30.2x, which is an acceptable speed. The LiteOn drive was the fastest at 39.9x while the Optorite was the slowest.

- Advanced DAE Quality

In Nero's CD Speed Advanced DAE test, the BTC drive reported an average speed of 21x, which is a poor performance, and a quality score of 100. CDSpeed reports that the drive can read Cd Text and Subchannel Data but not Leadin and Leadout.

- Support of 90/99mins AudioCDs

BTC managed to rip the contents of our 90/99min test discs successfully.

- 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 sIsland)

The BTC DRW1008IM performed well with our Key2Audio disc, managing to both read and rip. This wasn't the case with our other audio CD however, which uses CDS200 protection. The BTC DRW1008IM recognized the disc but unfortunately could neither rip or play the contents of the specific disc. For the same discs, the Optorite drive only had problems with the first track on the CDS200 protected disc, while the LiteOn managed to rip and play both.
