Benchmarks: CD Speed: CD-R, CD-RW, DVD-ROM
Nero's CD Speed burn tests are done twice, once
with a CDR rated to 1x-52x burn speed, and a CD-RW rated to 4x-32x. Each disk
was test with files of about 640MB in size. This test is done by simply placing
blank recording media into the burner and running CD Speed the
software will detect if it is CD-R or CD-R/W media and run the
appropriate tests.

The LG GSA-4120B does pretty well
for itself here in the CD-R/CD-RW burn tests. Both times the drive is able to
hit its maximum write speed.
CD Speed can also read DVD-ROM discs showing you
maximum transfer speeds, access times and CPU
utilization. The DVD data disc has about 3.78GB of data on it and is a retail
DVD-ROM disc, not burned on a DVD-/+R disc.

The average speed of the LG GSA-4120B is
very good, and access times are quick. CPU usage seems a bit on the high side,
but that's about it.
