DAE Tests
- Test Method:
We used CD DAE 99 v0.21 beta and EAC v0.9 prebeta 11 in order to check
the DAE performance of the various DVD-ROMs with various AudioCDs (both pressed
and CDR). The posted DAE results are the average of both applications, but
the CPU usage is only measured during the use of 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.
- Pressed AudioCD results:
The LiteOn is the absolute king of the DAE ripping tests. The drive managed
to reach around 31.9X of average DAE ripping speed, which is the fastest we
have ever measured for a DVD-ROM drive. The AOpen 1648 comes second with 22.8X
average and the Matsushita finishes last at only 15.5X:
- CDR AudioCD Results:
The LiteOn LTD163 continues to lead the race even with CDR media. The
drive actually performed better and reached 33.4X. The AOpen 1648 continues
to come second and the Matsushita SR-8586 is once again the last one:
- Advanced DAE Quality:
The Lite-On and AOpen drives completed the CD Speed 99 "Advanced DAE test" successfully, and got perfect score (100). The Matsushita SR-8586 produced 35 data and 1 sync errors and got a score of 99.2.
- Bad CDR Media results:
Despite the fact that CD Speed 99 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 to cause problems to most of the tested drives. We used CD DAE 99 software to rip the whole disc (756539616 sectors) and the results are quite interesting:

As the tests showed, the Lite-On LTD163 not only is a top performer but it can also produce very good quality wav files. The AOpen 1648 comes second with 54425 errors and the Matshita SR-8586 comes last with the largest amount of errors.
- Ripping 90 and 99min CDs:
AOpen 1648: The drive stops reading our 90min CD at 88mins and our 99min CD at 98minutes as Nero CD Speed v0.83 reports:
>> 
Lite-On LTD163: The drive reads both 90 and 99minute CDs without any problems:
>> 
Matshita SR-8586: The drive reads 90min CDs without any problems, but refused to perform the test with 99min CDs:
