CD Speed is a CD/DVD-ROM benchmark which can test the
most important features of a CD-ROM drive. In this particular test we use a
pressed CD-ROM with about 640MB of data as the test disk. Using a CD-R or CDRW as
the test disk may (or may not) impact the results slightly, so the pressed disk
is the de facto standard.

When we
compare the LG GSA-4082B drive to the others listed here, overall it performs
about the middle of the pack. Access time is a bit on the high side, but still
faster than the Plextor CD-RW.
CD Speed
is a CD-ROM benchmark which can test the most important
features of a CD-ROM drive. In this particular test we use a pressed Audio
CD with about 65 minutes of audio on it as the test disk. CDROM's in general have
a harder time processing audio data, and hence the results can be drastically slower than
that of data tests alone.

The LG
GSA-4082B is very fast when it comes to audio disc
speed, access time is about middle of the pack, not the fastest but not the
slowest either.
