- Writing Performance

The LG 4167B drive, supports 2.4x, 4x (CLV), 8x (ZCLV), 12x, 16x (PCAV) for DVD+R media and 2x, 4x (CLV), 8x (ZCLV), 16x (PCAV) for DVD-R media. Below is the list of supported burning speeds reported by Nero upon media insertion.

By using Nero CD-DVD Speed with a 16X DVD-R and a 16X DVD+R media, we are able to see the supported writing strategy for this burner. Click on each image below for a complete CDSpeed graph.

- DVD+R media @ 16X

The strategy used by the LG 4167B drive with 16+R media is P-CAV as reported by Nero CD-DVD Speed utility. The task started at 7.15X and finished at 15.99X max end speed. The elapsed time was 5:35mins, and the average reported speed was 12.65X.

- DVD-R media @ 16X

As with the DVD+R format, P-CAV writing strategy was used. The test started at 7.17X and climbed all the way up to a steady 16X, completing the task in 5:05mins. The reported average speed was 12.70X.

- Burning Tests

We burned 4315MB of data on various DVD±R, DVD±RW media. We used the maximum allowed writing speed for each disc.

As we stated in the beginning of this review, we received the drive with firmware revision DL10 with which we performed the first recordings. The first results were among the worst we have ever seen and for this reason we highly recommend you flash the drive to a newest firmware version, as we did upgrading to DL11, the latest at the time of this review.

• DVD-R/-RW media

With DVD-R media, the 4167B performed fast, with the majority of media burned at their designated speed. Notice the writing stability, with almost all media reporting more or less the same burning times. Worst writing came with the Optodisc 16X media, burned in 14:26mins, which is a 4X true speed burn.

• DVD+R/+RW media

The stable performance gave way to speed. We have many oversped cases, while all 16X media was burned at their designated speed, with fastest writing being that with Philips 16X DVD+R media.

- Comparison with other drives

As we saw previously, the LG can burn at 16X with times under 6 minutes, and hence managed to be the fastest among the comparison drives.

- DVD Overburning Tests

Using Nero CD-DVD Speed, we tested to see if the drive can overburn using DVD+R and DVD-R media. Unfortunately, the drive does not support overburning, giving the following error with all inserted media.

• DVD-R media

• DVD+R media

- DVD+MRW Tests

The drive doesn't support the Mount Rainier feature.
