DVD writing performance
In the tests below, we will explore DVD writing capabilities and performance of LG GSA-H50N. We will use Nero CD-DVD Speed to write various types of DVDs.
Summary
The following table lists all writing speeds and strategies used by LG GSA-H50N when writing DVD media:
Some of these strategies are presented below and compared to strategies used by similar 18x drives.
18x DVD+R
LG GSA-H50N uses an 8x-18x CAV (Constant Angular Velocity) strategy to write DVD+R media at 18x.
Average speed is 13.43x and full-disc burn time is 5 minutes and 16 seconds:
18x DVD+R writing
16x DVD+R
LG GSA-H50N uses a 7x-16x CAV (Constant Angular Velocity) strategy to write DVD+R media at 16x.
Average speed is 11.85x and full-disc burn time is 5 minutes and 50 seconds:
16x DVD+R writing
8x DVD+R
LG GSA-H50N uses a slower than usual 4x-8x Z-CLV (Zone-Constant Linear Velocity) strategy to write DVD+R media at 8x.
Average speed is 7.38x and full-disc burn time is 9 minutes and 10 seconds:
8x DVD+R writing
8x DVD+RW
LG GSA-H50N uses a 6x-8x Z-CLV (Zone-Constant Linear Velocity) strategy to write DVD+RW media at 8x.
Average speed is 7.73x and full-disc burn time is 8 minutes and 53 seconds, a noticeable improvement over LG GSA-H22N:
8x DVD+RW writing
10x DVD+R DL
LG GSA-H50N uses a 6x-10x P-CAV (Partial Constant Angular Velocity) strategy to write DVD+R DL media at 10x.
Average speed is 9.11x and full-disc burn time is 14 minutes and 16 seconds, a whole five minutes under LG GSA-H22N's time:
10x DVD+R DL writing
18x DVD-R
LG GSA-H50N uses an 8x-18x CAV (Constant Angular Velocity) strategy to write DVD-R media at 18x.
Average speed is 13.46x and full-disc burn time is 5 minutes and 4 seconds:
18x DVD-R writing
16x DVD-R
LG GSA-H50N uses a 7x-16x CAV (Constant Angular Velocity) strategy to write DVD-R media at 16x.
Average speed is 11.90x and full-disc burn time is 5 minutes and 30 seconds:
16x DVD-R writing
8x DVD-R
LG GSA-H50N uses a 5x-8x P-CAV (Partial Constant Angular Velocity) strategy to write DVD-R media at 8x.
Average speed is 7.38x and full-disc burn time is 9 minutes and 11 seconds:
8x DVD-R writing
6x DVD-RW
LG GSA-H50N uses a 6x CLV (Constant Linear Velocity) strategy to write DVD-RW media at 6x.
Average speed is 6.02x and full-disc burn time is 10 minutes and 10 seconds, 45 seconds faster than LG GSA-H22N:
6x DVD-RW writing
12x DVD-RAM
LG GSA-H50N uses a 6x-12x, 34-zone Z-CLV (Zone-Constant Linear Velocity) strategy to write DVD-RAM media at 12x, without verification.
Average speed is 10.06x and full-disc burn time is 5 minutes and 44 seconds:
12x DVD-RAM writing without verification
5x DVD-RAM
LG GSA-H50N uses a 3x-5x, 34-zone Z-CLV (Zone-Constant Linear Velocity) strategy to write DVD-RAM media at 5x.
Average speed is 4.71x and full-disc burn time is 11 minutes and 52 seconds:
5x DVD-RAM writing
Book type (bitsetting)
LG GSA-H50N supports bitsetting, and is capable of writing DVD+R and DVD+R DL (but not DVD+RW) with the DVD-ROM book type.
The drive comes preconfigured with DVD+R and DVD+R DL media set to be written with the DVD-ROM book type:

CD writing performance
One thing I would advise against is using any LG drive for TRT. Those drives have no problems with extremely poor burns. I have had a severely degraded Ritek G05 that would not read at all in any of my liteons, I put it in my LG and it did not slow down once during the rip. I've noticed this on a number of poorly burnt discs in the past and I have two LG drives to confirm that they are very good readers, too good when it comes to TRT.

Many things besides the quality of the disc can go wrong at high reading speeds. 16x DVD speeds mean interpreting 56 meters/180 feet per second of track covered with microscopic bumps. It makes me think of reading highway signs written in Braille - at supersonic speeds
The whole thing is a bit of a black art... a reading test can show a hint of a problem where the quality test sees none, and vice versa. The best we can do is to pick one reading drive for a review and stick with it until there is an apparent contradiction between a quality test and a reading test, as was the case here.
O meu dvd não abriu o computador e não roda nada!!!
