CD Recording Tests

- CD-R Writing Tests

To test the writing speed and writing method of the drive we used a blank 80min CD-R disc from TY and NeroCDSpeed to emulate the writing process.

The writing emulation process confirmed the 24x maximum writing speed of the BenQ. The drive used P-CAV writing strategy while the reported average speed was 23.53x. The process started at 18.20x and the speed increased until the 14min mark, after which and until the end of the writing process the speed was constant at 24x .

- Recording Times

We created an 80min data compilation with Nero Burning Rom and recorded it on a 700MB disc.

The results of the above graph were predictable since each device supports a different maximum writing speed. Therefore, the BenQ at 24x , finished the task after 4:11min while AOpen, was 30sec faster at 32x. LiteOn was about one minute faster than BenQ and the fastest of the comparison because of the 40x maximum writing speed.

In the above graph we have presented the writing speeds from the three drives for all avaliable recording speeds. As we can see, each writer supports different writting speeds for CD-R media. Moreover, even at the 24x maximum writing speed, the LiteOn was 13sec faster than the BenQ drive.

We used various manufacturers media to test the writing speed and media compatibility of BenQ and we summarized the results in the above graph. All tested discs produced similar writing times.

- CD-RW Writing Tests

To test the writing speed and writing method of the drive we used a blank 74min CD-RW disc from MC and NeroCDSpeed to emulate the writing process.

The disc was written with an end speed of 10.14x while the average reported speed was only 9.96 . The RW media was written with CLV.

Below we provide a comparison of the three drives where we used Nero Burning Rom software to burn a 651MB data compilation onto 24x US-RW media from MC.(For BenQ we used a 10x HS-RW from Plextor)

Because of the 10x maximum writing speed for CD-RW media, the resultant writing time for the BenQ is much higher than the other two devices.

- Packet Writing Tests

For the packet writing test we used the InCD packet writing software from Nero and a Plextor 10x US-RW media. The tested file is a 403 MB file (412.822 KB) and we used the drag and drop method with Windows Explorer to write the file from our hard disk onto the RW media.
