DVD drives
DVD drives are computer input devices that play, read and write DVDs. Similar to the DVD players that connect to a TV or home theater, they come in a variety of speeds and options (for details, see DVD player).

Each X Is 1.35MB Per Second
The first DVD (1x) transferred data at 1.35MB per second, and the number of X's is that number multiplied by 1.35MB (see list below). Each DVD X is equivalent to nine X's of CD speed because DVD 1x is 1.35MB and CD-ROM 1x is only 150KB. See CD-ROM drives and DVD.
