Benchmarks: CD Speed, Sandra 2003
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.

Audio and
data discs are not the same, and
so it is always a good idea to test the drive with each medium. In this
test with an audio CD, we can see average read times rank in
at about 20X, which is just about middle of the pack. CPU usage stays
low, and seek times are also quite good.

Sandra offers a good measure of data rates, and with
a drive index of 1687, things are standard, but not top of the pack. Access times
remain pretty good though.
