DVD Recording Tests

- Writing Performance

The Artec drive supports DVD+R and DVD-R writing. The maximum supported speed is 8X and 4X respectively. With the RW format, Artec supports 4X for DVD+RW and 2.4X DVD-RW.

8x DVD+R

4x DVD-R

According to the manufacturer's specifications the drive should be capable for 4x DVD-R recording. This was not confirmed from our tests with several media brands. The drive can only record DVD-R discs up to 2.4x.

- Burning Tests

The following graphs show the maximum writing speed for all available DVD formats. For comparison, we also include the writing times of the TEAC DV-W58G and Optorite DD0401 drives.

The drive had good writing times for the +R format. On the other hand, since the drive failed to burn -R media at the expected 4X speed, the writing times were somewhat high.

The following screenshots were taken from Nero, after successful burnings. The recording project is the same DVD-Video compilation for all tests.

• Philips 8x DVD+R

• Ritek 4x DVD-R (recorded at 2.4x)

• Mitsubishi Kagaku 4x DVD+RW

• Mitsubishi Kagaku 4x DVD-RW (recorded at 2.4x)

The table above presents writing speeds of the drive, for various media brands and formats.

- Packet Writing Tests

For this test we copied a 403 MB file (412.822 KB) from Hard Disk (on the same PC as the recorder) in to formatted RW media, through Windows explorer (drag and drop).
