DVD Recording Tests

- Writing Performance

Nero Burning Rom allows user to write to DVD-R media at 1X, 2X and 4X, when the media allow it of course. With some DVD-R media, you will only see 2X or 1X writing speed, since the drive automatically lowers the recording speed.

When we insert 2X DVD-RW media, we can choose the 1X or the 2X for the writing process.

We burned almost 4.7GB of data with Pioneer DVR-A05 in Pioneer 2X/4X DVD-R and 1X/2X DVD-RW media. The results are listed in the following table:

Pioneer DVR-A05 took 14:24 mins to write an almost full DVD-R 4.7GB disc. The same amount of data are written at 2X in 28:21 minutes. The recording time at 2X DVD-RW media is less than the half needed for recording in the 1X DVD-RW. Also notice that writing at 2X in DVD-RW media is faster than writing in DVD-R.

The following pictures come from Nero, after successful DVD-RW and DVD-R burnings. The amount of data is the same for all the tests.

- 4X DVD-R

- 2X DVD-R

- 1X DVD-RW

- 2X DVD-RW

- Media compatibility to 4X writing speed

We used the following DVD-R media, in order to determine which of them may work at the 4X writing speed. As the results showed, the A05 will write at 4X speed ONLY with certified 4X DVD-R media. The current 2X DVD-R media will be written at 2X while many Taiwaneze media (and the cheapest) only at 1X.

- DVD-RW Erase Time

Pioneer DVR-A03 finished the Nero "Quick erase" task at only 26 seconds. The media we used for this test was 2X DVD-RW.

- Packet Writing Performance

We used the same file/methodology we are using for our CD packet-writing test. Pioneer DVR-A05 needs 2:25 minutes to write / read the test file. The following picture is from Nero, when we inserted the 2X DVD-RW disc.

It seems that the drive supports the 2X reading and writing speed with 2X DVD-RW discs. The previous model supported only 1X.
