The CD results are very dependant on the disc being used.
We recommend either buying our discs (of course)
or making a standard test disc with our CD-Maker utility
Use the advanced CD test, with the RAW option over a long duration (at least a minute), then examine the graph to get the most interesting results. Some drives are slow to start and / or slow to reach their top speed. Also, make sure the drive is not already spinning when you start the tests to make it a fair test.
