Mitsumi CR-4809TE CD-RW

4. DAE Tests

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 drive 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

We used EAC v0.9 prebeta 11 to examine the drive's features. As the program reported, the drive doesn't "Caching" data, supports "Accurate Stream" and doesn't include "C2" error info. All 4 tested drives supports up to 40x (CAV) DAE speed.

- Pressed AudioCD results - (Click to see the Nero CD Speed graph)

The Mitsumi CR-4809TE performed very well with pressed Audio CDs but gets the last place since the competition is faster. The drive's average reading DAE ripping speed is 28.4X and also reported 7errors at the end of the process:

- CDR AudioCD results - (Click to see the Nero CD Speed graph)

The Mitsumi CR-4809TE improved its performance with CDR media and now gets the third place with LiteOn LTR-24102B. Its average reading performance is 28.8X and again produced 2 errors while reading the test disc:

- EAC Secure Extract Ripping mode

After many requests from numerous visitors 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 Mitsumi CR-4809TE gets a 100 score (best) in the Nero CD Speed Advanced DAE test. The drive's average reading speed was 29.15x and no errors were produced. As the following picture shows, the drive can read CD-Text/SubChannel Data:

- Bad CDR Media results

Despite the fact that CD Speed 99 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:

The Mitsumi CR-4809TE performed very well with our bad CDR test disc. The drive reports only 24 errors while reading our test disc at full speed! The only drive that beats it is the TEAC CD-W524E.

- Ripping 90 and 99mins AudioCDs

The Mitsumi CR-4809TE recognizes the 90min AudioCDs without any problems. However it seems to have a problem with the 99min CDs:
