- Writing Tests

We burned some DVD+R DL and DVD-R DL discs with data content. For this task we used "Create Data Disc" from Nero CDSpeed in order to burn the discs.

Mitsubishi Chemicals DVD+R DL 8X

According to CDSpeed, with Z-CLV strategy, the test started at 4.03X and maxed out at 8.06X, reporting an average speed of 5.68X. The test was completed in 21:15 mins. Note here, that the writing speed dropped before the layer change, and shot back up at the start of the second layer, greatly affecting the burning time. This is somewhat a confusing writing strategy...

Traxdata DVD+R DL 2.4X

While using Traxdata DVD+R DL 2.4X certified media, the drive retained the same speed all the way to the end, reporting an average speed of 2.39X and finishing at a speed of 2.42X with CLV writing strategy.

Mitsubishi Chemicals DVD-R DL 4X

No overspeeding here, where the MKM -R DL 4X certified media was burned at its designated speed. The test started at 4.03X and retained the same speed all the way to the end of the burn. WOPC enabled and with an average speed of 3.99X, the test was finished in 27:08mins.

Traxdata DVD-R DL 4X

As with the Verbatim media, the HP 840b performed the similarly with the Traxdata -RDL 4X certified media, completing the burn in 27:10mins.
