DVD Recording Tests

- Writing Performance

The BTC supports DVD-R/RW and DVD+R/RW writing. The maximum supported speed for DVD+R and DVD-R is 8x P-CAV and 4x CLV for DVD+/-RW media.

8x DVD+R

An 8x DVD+R disc from TY was used to check the 8x writing strategy of the drive. The software used was Nero CDSpeed, with its "create disc" function.

The drive started writing at 3.95x, and ended at 7.99x with an average speed of 6.34x.

Verbatim 8x DVD-R

The simulation with the 8x DVD-R was almost the same as with 8x DVD+R media. In this test we used Verbatim media.

Mitsubishi Chemicals 4x DVD+RW

Mitsubishi Kagaku 4x DVD-RW

- Burning Tests

The best recording times are illustrated in the following table. The values were taken after burning 4315MB of data on various DVD±R, DVD±RW media, using the maximum allowed writing speed for each disc. For comparison, we also include the writing times for the TDK 880N and Toshiba SD-R5272.

There is not much between the three drives, their times being very close. However, the TDK 880N had the fastest times with all the formats.

The table below presents the writing speeds, media name and media code for the various discs used.

- Packet Writing Tests

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