The speed, with which these DVD rippers work, depends on a number of factors. The DVD is ripped 8 times faster by using a 8x drive, than the speed with which it is played. Another factor affecting the speed of the ripper is the efficiency of CPU. A less efficient CPU can cause the DVD ripper to slow down as a number of CPU processes are involved in the ripping of a DVD.
A lot of disk space must be available at your computer and you can take care of it by cleaning the unwanted files, software and programs on regular basis. Many things running in the background at same time are sure to affect the efficiency of the ripper. A fast machine instead can speed up the whole process of ripping. You can switch to a 2ghz+ processor if you want some excellent results. Usually a free space of more than 40GB is recommended to avoid the situation of starting the process all over once again by the non-availability of the free space. So once you become perfect with your DVD ripper, you can download all your favorites in just a blink of eye.
