AOpen CRW1632 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 CRW1632 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 doesn't support "C2 Error info".

- Pressed AudioCD results: (click here to see the CD Speed 99 graph)
The AOpen supports up to 32x DAE with both pressed and CDR media. The drive uses full CAV as the main reading technology. However compared to the other competitors, AOpen CRW1632A is slower:

The drive has an average of 23.3x, staying far away from the top performer PX-W1610A. The LiteOn LTR-16101B comes second and Teac 516EB third.

- CDR AudioCD Results: (click here to see the CD Speed 99 graph)
The drive performs quite well with CDR media. The average DAE was around 23.5X:

- 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 CRW1632 performed excellently at the Nero CD Speed Advanced DAE quality test. The drive produced 0 data/sync errors and got a perfect score (100). LiteOn didn't perform as you might expect in the CD Speed 99 Advanced DAE test. The drive produced 58750 data errors, and got 98.1 score out of 100 (perfect). The drive cannot read "CD-Text" enabled AudioCDs and can read "SubChannel Data" (from audio tracks):

- Bad CDR Media results

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 only drive that managed to read the disc without reporting any error was the Teac 516EB! The Plextor drive came second with only 5069 errors. The LiteOn drive reported 155252 errors and as for the AOpen drive, performed very bad since almost 88.74% of the read data weren't correct.

- Ripping 90 and 99min CDs:

>>

As we can see from the above graphs, the AOpen CRW1632 doesn't have any problem ripping both 90min and 99min CDs.
