Nero's CD Speed burn tests are done twice, once
with a CD-R disc rated to 1x-52x burn speed, and again with a CD-RW rated to
4x-32x. Each disc was test with the same files, about 640MB in size. This test
is performed 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.
