CD reading performance
In the tests below, we will explore CD reading capabilities and performance of LG GSA-H50N. We will use Nero CD-DVD Speed to read various types of CDs.
Summary
The following table lists reading speeds and strategies used by LG GSA-H50N when reading CD media:
Some of these strategies are presented below.
CD-ROM
LG GSA-H50N reads CD-ROM at 19x-46x CAV (Constant Angular Velocity) speed.
With a pressed CD-ROM data disc, about 73 minutes in length, average speed is 33.61x and read time is 2 minutes and 16 seconds:
CD-ROM reading
CD-Audio
While only 1x speed is required to listen to sound stored on CD-Audio discs, it is useful to be able to read the discs at higher speeds when extracting the content of the disc to a hard drive.
LG GSA-H50N reads CD-audio at 17x-41x CAV (Constant Angular Velocity) speed.
With a 74-minute pressed CD-Audio disc, average speed is 30.08x and read time is 2 minutes and 35 seconds:
CD-Audio reading
CD-R
LG GSA-H50N reads CD-R at 21x-49x CAV (Constant Angular Velocity) speed.
Average speed is 36.70x and read time is 2 minutes and 17 seconds:
CD-R reading
CD-RW
LG GSA-H50N reads CD-RW at 18x-43x CAV (Constant Angular Velocity) speed.
Average speed is 32.13x and read time is 2 minutes and 36 seconds:
CD-RW reading
DVD 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.
