DVD Recording Tests

- Writing Performance

The BenQ DW1620 supports 16X DVD±R and 4X DVD+R DL writing.

The maximum supported speed for DVD±R is 16X (6X~16X CAV), 4X CLV for DVD±RW and 4X for DVD+R DL media.

Nero Burning Rom reported speeds are shown below.

The drive burns CLV at 2.4X and 4X, P-CAV at 8X/12X and CAV at 16X. With DVD-R/RW media, 1X/2X writing speeds are not supported, meaning older 1X/2X rated DVD-RW media won't burn at all. BenQ has found that 8X DVD+R media can over-speed up to 12X and even 16X with good burning quality. Firmware upgrades improve the compatibility list, meaning more media will be supported and burning quality improved.

By using Nero CD-DVD Speed's "create disc" function, we are able to see the 8X, 12X and 16X recording technology being used by the DW1620 burner. Click on the screenshot for the full CDSpeed graph.

- Burning Tests

We burned 4315MB of data on various DVD±R, DVD±RW media. We used the maximum allowed writing speed for each disc. With the current firmware (vB7H9) not many media are supported at 16X, especially for the DVD-R format. Future firmware releases are expected to support more media at 12X/16X for both DVD±R formats.

- DVD Overburning Test

Using Nero CD-DVD Speed, we tested if the BenQ DW1620 DL can overburn using DVD±R media. Unfortunately, the drive does not support overburning with DVD±R media.
