- Writing Performance

The maximum supported speed is 16X CAV for both DVD+R and DVD-R formats. For the DVD+RW the speed is 8X while for the DVD-RW 6X ZCLV.

By using Nero CD-DVD Speed with DVD-R and DVD+R media, we are able to see writing strategy of the drive for both formats at 16X burning speed.

16X DVD+R Single Layer writing

The drive completed successful DVD writing at 16X in 6.06mins. The test started at 6.68X, reached a maximum writing speed of 15.97X and reported an average speed of 11.74X.

16X DVD-R Single Layer writing

The drive completed successful DVD writing at 16X in 5:37mins. The test started at 6.69X, reached a maximum writing speed of 16.05X and reported an average speed of 11.96X.

- Burning Tests

DVD-R media

We burned a variety of DVD-R media of 16X and 8X enabled. Almost all media were burned at their named speeds, with the exception of the TY 8X -R media burned at 12X. Bust burn (time related) came with the Moser Baer media burned at 6:15mins.

DVD+R media

Once again all media burned at their named speeds while we had some overspeeds at 8X effective media. Notice the TY 8X which was actually burned at 16X speed with a time of 6:12 and good results which also happens to be the best burn (time related).

- DVD Overburning Test

DVD+R

DVD-R

Unfortunately, the drive does not support DVD overburning for both -R and +R media formats, giving the above error messages.

- DVD-RAM

Now we will see how the drive performs when a DVD-RAM media is inserted. According to the manufacturers specs, the drive can read and write DVD-RAM media, with the max speed of 5X.

As Maxell stated: "DVD-RAM is an advanced recording media format that offers a range of digital data applications. Its phase-change recording material allows discs to be re-recordable and erasable, and a superior defect management system ensures accurate recording and playback. DVD-RAM allows instant, random access to any location on the disc for fast and easy data reading and writing. Because DVD-RAM supports fast formatting and no finalizing, it is an extremely easy-to-use media. And with DVD-RAM, changes can be made directly on the disc without the need to transfer data to a hard drive first, speeding up the editing tasks..."

- Burning Tests

Using NeroCDSpeed, we got the following graph:

The test started at 4.97X burning speed and was completed 5.01X reporting an average speed of 4.86X. It took only 11:32mins to complete a full DVD-RAM writing, while with the Nero and a blank DVD-RAM, the reported time was roughly 30mins, as the drive uses the "Write and Verify" when burning DVD-RAM media.

- DVD+MRW Tests

The drive does not support the Mount Rainier feature.
