DVD Recording Tests

- Writing Performance

The maximum supported speed is 16X for DVD+R media while with DVD-R it is 8X, and for rewritable media 4X.

Nero Burning Rom reported speeds are shown below.

The drive burns P-CAV at 8X/12X and CAV at 16X.

We used Nero CD-DVD Speed and its "create disc" function, in order to see the 8X, 12X and 16X recording technology being used by the F16 recorder. In the following graphs we used CMC 16X DVD+R media.

8X DVD+R Single Layer writing

The drive completed successful DVD writing at 8X in 8:11mins. It started writing at 6.69X, reached a maximum writing speed of 8.05X and reported an average speed of 7.98X.

12X DVD+R Single Layer writing

The start, end and average speeds for the Memorex were 6.67X, 12.08X and 10.91X respectively. The task finished after 6:17min

16X DVD+R Single Layer writing

The drive completed successful DVD writing at 16X in 5:48mins. It started writing at 6.66X, reached a maximum writing speed of 16.00X and reported an average speed of 11.97X.

Below is a table with the average writing speeds for various 16X recorders as measured by Nero CDDVDSpeed, showing that the Memorex achieved the fastest average 16X recording speed:

- Supported media list/Burning Tests

We burned 4315MB of data on various DVD±R and DVD±RW media. We used the maximum allowed writing speed for each disc. With the current firmware (vB7H9), there's not a lot media being supported at 16X, especially for the DVD-R format. Future firmware releases are expected to support more media at 12X/16X for both the DVD±R formats.

- Writing Time Results

DVD-R media

The writing strategy of the F16 with DVD-R media is Z-CLV.

The media from Traxdata with ID R04, certified for 16X speed, is not included in the current firmware and so the maximum speed for that media was 8X.

Some media had problems while playing back in our test DVD players. More details in the table below:

- Comparison with other drives

With DVD-R media, the Memorex was significantly slower than the other two drives due to its 8X supported speed which for the Pioneer and BenQ drives is 16X. On the other hand, with DVD+R media, all three drives support the same maximum speed of 16X, but there is a large difference in the reported times where the Pioneer drive was 86 seconds slower than the Memorex.
