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.

By using Nero CD-DVD Speed with DVD-R and DVD+R media, we are able to see the 8X, 12X and 16X recording technology being used by the recorder for +R media, and 8X recording technology for -R media.

8X DVD+R Single Layer writing

The drive completed successful DVD writing at 8X in 8:11mins. The test started 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 test started at 6.67X, reached a maximum writing speed of 12.08X and reported an average speed of 10.91X.

- Burning Tests

DVD-R media

The drive supports up to 8X writing speed with -R media. Best performance came from DataWrite 8X media that was burned in 9:12mins. Overspeed burning was not introduced in any instance, and all media were burned at their intended speed.

DVD+R media

Best performance was reported with CMC Magnetics media that was burned in 5:56mins (16X writing speed). Again, no overspeed burning technology is introduced, and all media was burned at their intended speed.

- Comparison with other drives

With DVD-R media, the LiteON drive was slower than the other two drives due to its 8X supported speed. On the other hand, with DVD+R media, the drive performed well, being the fastest 16X recorder.

With DVD Re-Writable media, all drives support the same speed. The LiteON was again the fastest of all three drives, while the Philips DVDR1640P was the slowest.
