AOpen EHW-4048U CD-RW - Page 5

DAE Tests

- DAE features

- Pressed AudioCD

The AOpen drive got the first place with 33.8X. At the default reading speed, the DAE performance was good with 29.3X, while the CRW-F1DX gets the second place with 30.7X

- Audio CD-R media

With CD-R media, the EHW-4048U had a low performance of 20.4X when it read at the default speed, but under the 'Turbo' mode it got the first place with 33.6X average reading speed.

- EAC Secure Extract Ripping mode

EAC's secure extract ripping mode results, which ensures maximum produced WAV quality. Note that for each drive we used the built-in detection function:

- Advanced DAE test

All the drives got a "100" score. The DAE speed for the AOpen drive under the 'Turbo' mode is 35.12X. The drive can read CD-Text and Subchannel data as the Advanced DAE test reports.

- 40X reading speed

- 48X reading speed

- Bad CDR Media results

We used CD DAE software to rip the whole disc (756539616 sectors) to the hard disk.

The condition of the disc can be considered as very bad, so the purpose of this test is not to get the best results with zero read errors, but to estimate the capabilities of the drive. The drive locked its reading speed at 8.3X and ended the test with a low error rate (2.62%).

- Ripping 90 and 99mins AudioCDs

- Reading/Ripping Protected AudioCDs

For the test procedure we used 2 protected AudioCDs, which we tested in both recognition and ripping (with EAC BURST mode) processes:

* Pressed AudioCD with Sony Key2Audio (Celine Dion - New Day Has Come)
* Pressed AudioCD with Cactus Data Shield 200 (Natalie Imbruglia - White Lilies Island)

The AOpen EHW-4048U was able to rip CDS200 but not Key2Audio protected Audio discs...
