Toshiba SD-R1202 CD-RW / DVD combo

4. DAE Tests

TOSHIBA SD-R1202 COMBO IDE CD-RW/DVD-ROM - Page 4

DAE Tests

- Test Method

We used CD DAE 99 v0.3 beta and EAC v0.9 beta 2 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. We made a full CD Rip starting from the first to the last track of the CD. The Average DAE reported speeds are displayed in the test graphs.

- DAE features

As EAC v0.9 beta 2 reported, the drive does not support "Caching" and supports "Accurate Stream" and "C2 Error info".

 

- Pressed AudioCD results

The DAE ripping speed of Toshiba SD-R1202 is not as high as we could expect. The average DAE ripping is 15.7x and this might be a drawback for the drive.

- CDR AudioCD Results

In the CDR DAE test, the drive kept the low average speed and additionally produced 20 reading errors.

- EAC Secure Extract Ripping mode

EAC "secure" extract ripping mode ensures the maximum quality of the produced WAV files, during audio extraction. Note that for each drive we used the build-in detection function:

- Advanced DAE Quality

Toshiba SD-R1202 completed the Nero CD Speed "Advanced DAE test" with a "86.1" quality score, since it produced 176250 data errors. The speed results were low as expected.

The average reading speed was 15.37X and Nero CD Speed reports that it can read "CD-Text" enabled AudioCDs, among with "SubChannel Data".

- 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:

Toshiba extracted the audio files to the hard disk at 15.6x average speed, as in the previous tests. The drive does not lower the ripping speed due the bad condition of the test disc and the produced read error rate was just 0.01%. The performance is good and only PlexWriter PX-W1610A is faster and possibly more accurate.

- Ripping 90 and 99mins AudioCDs

The drive recognizes 90min AudioCDs and when 99 min CDs are inserted, it stops reading at 98 min.

- Reading/Ripping Protected AudioCDs

For the test procedure we used 3 protected AudioCDs, which we tested in both recognition and ripping (with CD DAE v0.3b/EAC v0.9 beta2) processes:

* Pressed AudioCD with Sony Key2Audio
* Pressed AudioCD with Cactus Data Shield 200 (Natalie Imbruglia - White Lilies Island)
* CDR AudioCD protected with Cactus Data Shield (CDS100) - made with Clone Audio Protector v1.1 (adding 30 secs lead-out)

The Toshiba drive can partly handke only the "CDS200" audio protection. The drive can rip all the tracks but the first.
