- Writing Performance

Now we will check the burning performance with DVD media. Below, the available writing speed list can be seen, as reported by Nero Burning Rom.

Using Nero CDSpeed with DVD-R and DVD+R media, we are able to see the 16X writing strategy of the SONY burner.

- DVD+R media @ 16X CAV

- DVD-R media @ 16X CAV

The drive supports 16X CAV strategy for both DVD+R and DVD-R formats. Click on the images above for the complete CDSpeed screen.

- Burning Tests

For our tests we used the media in following tables.

DVD-R media

The writing times were good from the SONY burner, which managed to record at 16X speed in less than 6 minutes for all media, with the exception of PRODISCF02, where although it reported successful burning at 16X, the time resembles 8X rather than 16X. It seemed as though the drive had to slow down in speed, in order to prevent the disc from being wasted. We didn't notice any overspeeding even with recognized media.

• DVD+R media

The compatibility list for 16X DVD+R media seems to be quite large for the Q30A. With all of the discs we tried, we didn't notice any recording speed lower than the disc's certified.

- Comparison with other drives

There is not a lot to comment about here other than very good times from the SONY drive (the lower the better).

- DVD Overburning Tests

The SONY DW-Q30A cannot overburn with DVD media.
