CD writing performance
In the tests below, we will explore CD writing capabilities and performance of LG GSA-H50N. We will use Nero CD-DVD Speed to write various types of CDs.
Summary
The following table lists all writing speeds and strategies used by LG GSA-H50N when writing CD media:
Some of these strategies are presented below and compared to strategies used by similar 18x drives.
48x CD-R
LG GSA-H50N uses a 22x-49x CAV (Constant Angular Velocity) strategy to write CD-R media at 48x.
Average speed is 36.86x and full-disc burn time is 2 minutes and 38 seconds:
48x CD-R writing
24x CD-R
LG GSA-H50N uses a 16x-24x Z-CLV (Zone-Constant Linear Velocity) strategy to write CD-R media at 24x.
Average speed is 22.30x and full-disc burn time is 3 minutes and 49 seconds:
24x CD-R writing
32x CD-RW
LG GSA-H50N uses a 16x-24x-32x Z-CLV (Zone-Constant Linear Velocity) strategy to write CD-RW media at 32x.
Average speed is 25.82x and full-disc burn time is 3 minutes and 31 seconds:
32x CD-RW writing
12x CD-RW
LG GSA-H50N uses a 10x CLV (Constant Linear Velocity) strategy to write 12x CD-RW media.
Average speed is 10.02x and full-disc burn time is 8 minutes and 32 seconds.
10x CD-RW writing
Features
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.
