CD Write Tests
1.
CD-DVD Speed - CDR Media
The LG GSA-4120B is capable of writing to CDR's at a maximum speed of 40x. We
used a wide variety of media to test its 40x capabilities.

The LG GSA-4163B uses the slower Z-CLV method of
writing to CDR media. Writing starts at 16x and the 40x zone is reached
at about the 50min mark. The average write speed was 31.70x.

In our actual write tests, the 4163B wrote
exactly 695MB of data in 3:25 minutes. As always, I gathered a variety
of media in order to test compatibility and record write times.
The table below shows the results...

As I saw with previous models, CDR media
compatibility was excellent. It wrote to all discs at their rated speed
and was able to write to Imation 24x "music" CDRs at 40x with no
playback issues.
How about write quality? Let's have a look
at the results using Nero's disc quality test. We used a supported Lite-On
drive for the write quality tests. The results are shown below...

With CD media, this is measured by the number of
C1 and C2 errors. All discs will report a certain number of C1 errors, but
what you should be more concerned with is the number of C2 errors reported.
Fortunately, there were no C2 errors reported with Philips 40x discs and
overall write quality was very good.
2. CD-DVD Speed - CDRW Media

The LG GSA-4163B is capable of writing to CDRW
media at 24x. Unfortunately, like the previous models, it was unable to
write at this speed to either of the "Ultra Speed" discs used in testing.

CDR Brand |
Write Speed |
Write Time |
| Memorex (Ultra Speed) 16~24x |
16x |
5:42 |
| Ritek 16~24 24X CDRW |
16x |
5:47 |
The drive wrote only at 16x to both Memorex and
Ritek CDRW discs capable of 24x writing.
3. Over-burning and 99min CDR Media

The LG GSA-4163B does not support 99min CDRs but
fortunately, unlike the previous models, it will overburn up to 94min without
issues. In our tests, anything above 94min failed. What was quite
good was the ablility to write to Melody branded 99min media at 40x.
