High Quality Content by WIKIPEDIA articles! In computer jargon, the speed at which data is written to (or read from) an optical disc (like a CD or a DVD) is shown as a multiple of X. For example, writing to a DVD at 8X will be much faster than writing to it at 4X. Modern Compact Discs support a writing speed of 52X and higher, and some modern DVDs support writing at 16X or higher. It is important to notice that the speed of 1X in CD writing is not the same as the speed of 1X when writing to a DVD. When writing to a DVD at 1X, the data is transferred at a speed of approximately 1.32 MB/s; in contrast, a CD at 1X is written at 150 KB (153,600 bytes) of data (CD-ROM Mode 1) per second. Thus, in brief, one X in DVD writing speeds is about 9 times more than one X in CD writing speeds. However, these speeds are not constant, and depend on the type of data written to the disc.
