Let us summarize the most important positive and negative points below:

The main positive points:

The LG GH22LP20 is a fast drive as far as writing CD-R and DVD±R media                                                    is concerned, recording some of the fastest times on DVD±R discs burned in our reviews.

The LG GH22LP20 wrote our tested DVD±R/±RW/DL media with generally very good quality.

The LG GH22LP20 was also able to burn selected DVD±R media at faster than its rated speed.

The LG GH22LP20 is a reasonably well built drive. Noise levels, even at 22X are not intrusive and DVD-Video playback noise levels are low.

The main negative points:

CD-RW (high speed 32X) writing quality on the LG GH22LP20 needs to improve.

DVD-Video extraction at 6X speed is slow compared to other drives.

To sum up, this is what we would say:

“LG GH22LP20 is a solid performer and an excellent choice for reliable CD and DVD burning at record speeds. It effortlessly produces quality burns faster than most other drives to date. We highly recommend it.”
