LiteOn LTR-16101B CD-RW

4. DAE Tests

Lite-On LTR-16101B IDE CDR-W - Page 4

DAE Tests

Test Method
We used CD DAE 99 v0.21 beta and EAC v0.9 prebeta 9 software in order to check the DAE performance of the Lite-On LTR-16101B 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 9 to examine the drive's 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 Lite-On supports up to 32x DAE with both pressed and CDR media. The drive uses P-CAV as the main reading technology. Teac uses the same technique also but Lite-On seems faster as the test results showed:

The drive has an average of 28x, staying far away from the top performer PX-W1610A. The Sanyo cannot follow and Teac stays behind with 26.4x

- CDR AudioCD Results: (click here to see the CD Speed 99 graph)
The drive performs quite well with CDR media. Again, you will notice the 32x max DAE ripping speed and the average result was around 27.3x, second best behind PX-W1610A:

- Advanced DAE Quality

The Lite-On 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 rest competitor drives easily pass the quality test and got the perfect score. The average reading speed was 28.05x and as we can see from the following picture, the drive can read "CD-Text" enabled AudioCDs and "SubChannel Data" (from audio tracks)..

- 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:

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 Lite-On drive reported 155252 errors and as for the Sanyo drive, you had better forget it. It simply refuses to read the dirty disc and reports read error.

- Ripping 90 and 99min CDs

As we can see from the above graphs, the Lite-On 16101B doesn't have any problem ripping 90min CDs, and refused to recognize written 99min CDs.
