Data CD Reading Tests

In order to test the reading performance of BenQ we used the latest version of NeroCDSpeed and different type of media proportionately to the test.
- Pressed CD results (Click for CDSpeed results)

To check the reading performance of BenQ with pressed CD media, we used NeroCDSpeed and a data pressed disc.

BenQ performed very well in the pressed disc reading test. The drive returned back the fastest start, end and average reading speeds. The disc was read under CAV mode, and the test confirmed and surpassed the manufacturer's specifications for 40x maximum reading speed.

Besides the fast reading speed of the BenQ drive with the tested pressed media, the above graph shows that the drive logged in very fast seek times. The drive proved to be faster than the other two drives in all three tested modes. With the full seek, the BenQ was 35ms faster than the LiteOn.

- CD-R Media results (Click for CDSpeed results)

To check the reading performance of BenQ with CDR media, we used NeroCDSpeed and a clone of the previous tested pressed media.

The BenQ drive returned the fastest reading speed of the comparison. The tested writer was faster in all three modes with a start speed of 18.41x, end speed of 44.28x and average speed of 33.07x. The average speed of the BenQ is plus 1.7x faster than Aopen's and plus 1.82x faster than LiteOn's.

The seek times test comes to confirms that BenQ is a very fast CD-R reader. The drive returned by far, faster seeks times in comparison with the other two drives. As shown in the above graph, the drive's full seek time was 62ms and 18ms faster than LiteOn's and Aopen's respectively.

- ReWritable Media (Click for CDSpeed results)

To check the reading performance of the BenQ with HS-RW media, we used NeroCDSpeed and a HSRW disc from Mitsubishi Chemicals.

According to specifications, the BenQ drive supports 40x maximum reading speed under CAV with an access time of 120ms for high speed rewritable CD-R media. The supported speed, reading strategy and seek times were confirmed by NeroCDSpeed as shown in the above graph. The test finished at 42.92x end speed for the BenQ with a full seek time of 159ms.
