DVD Recording Tests

- Writing Performance

The CyberDrive DX082D supports DVD+R/RW writing. The maximum supported speeds are 8X and 4x respectively.

We used an 8x DVD+R disc form Mitsubishi Chemicals in order to check the 8x writing performance of the drive. The software used was Nero CDSpeed and its "create disc" function.

The writing procedure started at 6x and after burning approximately 500MB the speed reached 8x. The process continued as illustrated below. This behavior is normal according to the manufacturer and it is similar to that of the Philips DVR824P, not surprising since they both carry the same NEXPERIA chipset.

As a side note, the test finished at 8.08x confirming the stated specification speed of 8x for DVD writing. The average speed was 7.6x.

Below is a screen shot of CDspeed writing test results with a 4x DVD+RW media from Mitsubishi Chemicals.

Once again the drive confirmed the manufacturers stated specifications for 4x DVD+RW writing. The test showed a solid writing speed of 4x.

- Burning Tests

We burned 4315MB of data on various DVD+R, DVD+RW media. We used the maximum allowed writing speed for each disc. The best recording times are illustrated in the following graph. For comparison, we also include the writing times of the Philips DVDR824P, Plextor PX-708A and Optorite DD0401 drives.

According to the table above CyberDrive proved the fastest among the drives when it comes to DVD+R media. It needed 07:48 min to burn our compilation. Plextor and Philips burned the same compilation in almost the same time, with a few seconds delay. Optorite was the slowest with over a minute's difference.

The same cannot be said of DVD+RW media. All the drives needed around the same time to write the project. The Plextor drive was faster with only three seconds difference from the next fastest.

The following screenshots are from Nero, after successful burnings with 8x DVD+R and 4x DVD+RW, both from Mitsubishi Chemicals. The amount of data is the same for all the tests.

• Mitsubishi Chemicals 8x DVD+R

• Mitsubishi Chemicals 4x DVD+RW

The CyberDrive DX082D adjusts the recording speed according to the inserted blank DVD disc. In the following table are the maximum permitted writing speeds with various media.
