AOpen CRW2440 CD-RW

4. DAE Tests

AOpen CRW2440 IDE CDR-W - Page 4

DAE Tests

- Test Method:
We used CD DAE 99 v0.21 beta and EAC v0.9 prebeta 11 software in order to check the DAE performance of the AOpen CRW2440 with various AudioCDs (both pressed and CDR). The posted DAE results are the average of both applications, but the CPU usage was only taken from CD DAE 99, since EAC occupies the system a lot more. As a last note, we used the "BURST" reading mode of EAC. We made a full CD Rip starting from the first to the last track of the CD. The Average DAE reported speed along with the CPU Usage is displayed in the test graphs.

- DAE features:
As the program reported, the drive doesn't "Caching" data, supports "Accurate Stream" and "C2 Error info".

 

- Pressed AudioCD results: (click here to see the CD Speed graph)
The AOpen supports up to 40x DAE with both pressed and CDR media. The DAE ripping performance was very good but the PleXWriter PX-W2410A still holds the first place with 30.1X average DAE speed:

- CDR AudioCD Results: (click here to see the CD Speed graph)
The drive performs better with CDR media. The drive reaches 29.6X DAE speed but needs further improvement to get the first place:

- EAC Secure Extract Ripping mode:

After many viewer-requests we have added the EAC's secure extract ripping mode results, which ensures maximum produced WAV quality. Notice that for each drive we used the build-in detection function:

- Advanced DAE Quality:

The AOpen CRW2440 performed excellently at the Nero CD Speed Advanced DAE quality test. The drive produced 0 data/sync errors and got a perfect score (100). The drive can read "CD-Text" enabled AudioCDs, despite the fact that CD Speed reports it doesn't and can read "SubChannel Data" (from audio tracks):

- Bad CDR Media results: (click here to see the CD Speed 99 graph)

Despite the fact that Nero CD Speed Advanced DAE test stretches drive's mechanism to the max, we decided to do real life tests with a scratched disc. The disc was dirty, and with some light scratches, enough in order cause problems to most of the tested drives. We used CD DAE 99 software to rip the whole disc (756539616 sectors) and the results were very interesting:

As the tests showed, the AOpen CRW2440 performs very badly when CD has scratches and dust. The drive produced 58476010 errors which mean that 77.29% of the read data were false. The LiteOn has great performance with 25.7X DAE speed and only (?) 345 errors. The PleXWriter PX-W2410A cannot recognize the disc and the TDK CyClone 241040 has the best behaviour with 0 errors.

As we can see from the above graphs, the AOpen CRW2440 doesn't have any problem ripping both 90min and 99min CDs.
