When burning a CD what is the difference between 12x and 48x?

Answer 1

How long does it take to write a CD-R or CD-RW disc?

The amount of time taken to write a disc depends upon the speed of the recorder, the writing method used by the recorder and the amount of information required to be written. Recording speed is measured the same as the reading speed of ordinary CD-ROM drives and players. At single speed (1x) a recorder writes 150 KB (153,600 bytes) of data (CD-ROM Mode 1) per second and at a multiple of that figure at each speed increment above 1x.
