CyberDrive CW038D CD-RW

4. DAE Tests

CyberDrive CW038D 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 CyberDrive CW038D 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 do "Caching" data, it supports "Accurate Stream" and doesn't support "C2 Error info".

 

- Pressed AudioCD results: (click here to see the CD Speed 99 graph)
The CyberDrive supports up to 32x DAE speed with both pressed and CDR media. The drive uses full CAV as the main reading technology. However, compared to the other competitors, CyberDrive CW038D seems to have the lowest DAE performance:

The drive has an average of 24.2x, staying far away from the top performer PX-W1610A, which leads the race with 30.3X(!). The LiteOn LTR-16101B comes second with 28.0X and Teac 516EB third with 26.4X.

- CDR AudioCD Results: (click here to see the CD Speed 99 graph)
The drive performs the same as with the pressed media. The average DAE is slightly lower and reaches 23.6X, far away from the top:

- EAC Secure Extract Ripping mode:

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

- Advanced DAE Quality:

The CyberDrive CW038D performed marvellous in 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 and can read "SubChannel Data" (from audio tracks) as the test results indicate:

- Bad CDR Media results:

Despite the fact that Nero CD Speed Advanced DAE test stretches a 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 proved, the CyberDrive's performance with bad AudioCD media is not very good. The drive stops reading after 5secs and therefore you cannot rip the wavs to HD. Other drives don't have any problems with it and Teac 516EB is the champion with 0 errors.

- Ripping 90 and 99min CDs:

>>

As we can see from the above graphs, the CyberDrive CW038D doesn't have any problems ripping a 90min Audio CDR media. However it stops reading around 90mins, as the Nero CD Speed test showed.
