When we burn the actual order to ensure the stability and content of the recording complete, will reduce the speed to burn. Because the DVD burning CD burning faster than improve the lot of the market in the DVD recorder function of the highest recording speed of 20 speed, for 2 to 4x recording speed per second data transfer capacity of 2.76M ~ 5.52MB, burning a Zhang 4.7GB of DVD discs takes about 15 to 27 minutes; and 8-speed recording need only 7-8 minutes, just burn a CD-R than the speed a little slower, but considering the amount of data to burn , faster DVD burner drive is clearly an advantage.
