DVD Recording Tests

- Writing Performance

The maximum supported speed for DVD+R is 16X (6X~16X CAV), while for DVD-R is 8X (P-CAV), 4X CLV for DVD±RW and 2.4X for DVD+R DL media. The current competition offers 16X for both DVD+ and DVD-R writing speeds and also higher DVD+R DL writing speeds, 4X.

Nero Burning Rom reported speeds are shown below.

By using Nero CD-DVD Speed's "create disc" function, we are able to see the 8X and 16X recording technology being used by the DVDR1640P recorder. For the following graphs, we used Philips' media.

  • 16X DVD+R Single Layer writing

The drive completed successful DVD+R writing at 16X in 5:49mins. It started writing at 5.07X, reached a maximum writing speed of 16.02X and reported an average speed of 11.49X.

  • 8X DVD+R Single Layer writing

With DVD+R at 8X, the drive needed 8:27mins to complete the task. It started at 4.27X and reached the maximum speed of 7.99X reporting an average speed of 7.70X.

  • 8X DVD-R Single Layer writing

The writing simulation started at 6.68X and finished at 7.99X with an average speed of 7.92X. The task finished after 8:07 minutes.

Below is a simulation graph with DVD-R media at 16X. As we mentioned in the introduction, the drive arrived in our labs with firmware revision P2.1. With this firmware, the drive supported up to 16X for the minus format. After the release of the revision P2.2, the speed was lowered to 8X for higher writing reliability.

The following table contains some 16X recorders, reporting the average writing speeds as measured by Nero CDDVDSpeed, showing that the Philips DVDR1640P is the second fastest 16X recorder:

- Supported media list/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 (P2.2), many media are allowed to write at 16X but only for the DVD+R format, since with the minus format they are restricted to 8X. Future firmware releases are expected to changes this.

- Writing Time Results

  • DVD+R media

Several Nero screenshots are placed below:

  • DVD-R media

The following table illustrates more supported media for 16X speed, most of them haven't yet been released to the public ;-)

Below are two Nero screenshots for the Philips DVDR1640P:

- Comparison with other drives

The Philips DVDR1640P is the fastest writer at 16X for both ±R formats as the test results showed. The ASUS and Pioneer drives cannot compete, due to their Z-CLV implementation.

With DVD re-writable media, the Pioneer and ASUS burners are faster with -RW media but slower with +RW.

- DVD Overburning Test

Using Nero CD-DVD Speed, we tested if the Philips DVDR1640P DL could overburn using DVD±R media. Unfortunately, the drive does not support overburning with DVD±R media.

- DVD+MRW Tests

The drive doesn't support the Mount Rainier feature.
