- Writing Performance

The maximum supported speed is 8X Z-CLV for both the DVD+R and DVD-R formats. For DVD+RW and the DVD-RW media, max speed is 4X CLV.

By using Nero CD-DVD Speed with DVD-R and DVD+R media, we are able to see the writing strategy of the drive for both formats at 6X burning speed.

• 8X DVD+R Single Layer writing

The drive completed successful DVD+R writing at 6X in 13:06mins. The test started at 2.45X, reached a maximum writing speed of 6.13X and reported an average speed of 5.28X.

• 8X DVD-R Single Layer writing

The drive completed successful DVD-R writing at 6X in 13:05mins. The test started at 2.03X, reached a maximum writing speed of 6.06X and reported an average speed of 5.31X.

- Burning Tests

• DVD-R media

We burned a variety of 8X enabled DVD-R media. Even though some media were burned at their certified speeds, the burn times resembled more of a 4X burn than 8X. While most of the times are slow, Datawrite Titanium media reported a "record" time of 42:10! Totally unacceptable, which, as we will see later on, also resulted in a bad burn.

• DVD+R media

Different format, same scenario. All writing times resemble 4X burning speed and as we will see later on with this media as well, even at this low speed, the drive could not produce good quality.

- DVD Overburning Test

• DVD±R

The drive does not support DVD overburning for both the -R and +R media formats, giving the above error messages.
