DVD Recording Tests

- Writing Performance

TEAC DV-W58G supports DVD-R/RW and DVD+R/RW writing. The maximum supported speed is 8x for DVD+R and 4x for DVD-R. With RW format, TEAC supports 4x for DVD+RW and 2x for DVD-RW.

4x DVD-R

To test the performance of the TEAC DV-W58G with DVD-R writing process, we used NeroCDSpeed to emulate the process and a TY DVD-R, certified at 4x writing. After the end of the test, the software reports that the drive wrote the disc under CLV, with an average speed of 3.96x, while the start speed was 3.95x and the end speed 4.11x.

8x DVD+R

With plus format, the TEAC supports 8x writing speed and uses the Z-CLV writing strategy. For this test we used Nero`s CDSpeed "create disc" function. The software reports that the write process started at 6.13x and finished with an end speed of 8.10x. As we can see from the picture below the drive increased the speed after the 1.3GB address mark on the disc.

4x DVD+RW

With DVD+RW format, drive supports 4x CLV writing method. After the end of the test, manufacturers specifications were confirmed with start and end speed at around 4x.

2x DVD-RW

With DVD-RW format, TEAC supports 2x writing speed. After the end of the test, the software reports that the disc was written under CLV mode with average writing speed 1.99x.

- 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 Sony DRU-530A and Pacific Digital 8xDVD drives.

There is no major difference between the drives except for DVD+R media where the Sony was slightly slower. Despite the closeness of the comparative times, the TEAC drive wa the fastest among the three.

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

• MKM 8x DVD+R

• TY 4x DVD-R

• MCC 4x DVD+RW

• JVC 4x DVD-RW

The table above presents writing speeds of the drive, for various media 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).
