CD Read Tests
In
this review, I'll be doing things a little different. Considering most
will probably consider upgrading from the LG GSA-4120B, I will provide a
comparison between the 4120B, 4160B and 4163B throughout this review.
1.
CD-DVD Speed - Pressed CD
In our transfer rate tests with a pressed CD,
the results are fairly similar in comparison, with the new 4163B taking a
slight lead on previous models.
Seek times were also similar in comparison, but
the the older 4120B shows the lowest seek times.
Finally, we see a significant improvement in CPU
Usage over the older GSA-4120B, but fairly similar in comparison to the
GSA-4160B.
2. CD-DVD Speed - CDR Media
With CDR media, the new 4163B performs slightly
better than the previous models.
Seek times with CDR media were a different
story. There is practically no improvement over previous models.
Now, the 4163B does show some significant
improvement in CPU Usage when compared to the 4120B.
3. CD-DVD Speed - CDRW Media
Most drives struggle a bit with CDRW media.
However, the LG drives all perform well and results of the transfer rate tests
are practically the same in comparison.
Unlike the results with CDR media, the new LG
GSA-4163B showed the lowest seek times with CDRW media.
CPU Usage was again much lower than the older
4120B and similar to those of the 4160B.
4. DAE - Advanced Quality Tests
The GSA-4163B performed well in our advanced
digital audio extraction tests. While the average speed was a bit slow,
it got a perfect score and passed all on-the-fly copying tests. It was
only unable to read the leadout info on the disc.
