The Burst rate test measures the maximum possible transmission rate from the optical drive to the computer.   
Since optical drives are usually connected to the IDE channel of a motherboard with the corresponding cable, the test result in this case shows the transmission speed of the IDE channel.
If the optical drive is connected in a different manner, the test is useful nevertheless. You can use the result to check whether the connection is fast enough for a high burning speed.
The result of the measurement is shown in the Interface area, to the right of the graph. The value in the Burst rate display panel should always be greater than the maximum speed of the optical drive (e.g. greater than 21 MB/s for a DVD burner with 16x write speed).

 

 
 
The test results are only meaningful if data from the disc inserted in the drive is cached. Since many optical drives do not cache audio data on the hard drive, we recommend using data CD’s for this test.
 
Write Speed
The write speed indicates the speed at which a drive can write data to the optical storage medium, e.g. 8x or 16x speed.
