DVD-ROM drive
‡
‡ Data on a DVD-ROM is read at a variable transfer rate, ranging from 6.6X at the innermost track to 16X at
the outermost track (the data transfer standard 1X rate is 1350 kbytes/s). The average data transfer rate is
11.3X (15,255 kbytes/s). Data on a CD-ROM is read at a variable transfer rate, ranging from 17.2X at the
innermost track to 40X at the outermost track (the data transfer standard 1X rate is 150 kbytes/s). The
average data transfer rate is 28.6X (4293 kbytes/s).
DVD-ROM read: 16X (maximum performance).
CD-ROM read: 40X (maximum performance).
CD-RW drive
**
**CD-RW writing speed may vary, depending on the media. The maximum writing speed is 8X (1X = 150
kbytes/s) for the CR-R and 4X for the CD-RW. The maximum reading speed is 32X for the CD-R and 20X for
the CD-RW.
CD-RW read: 20X (maximum performance).
CD-RW write: 4X (maximum performance).
CD-R read: 32X (maximum performance).
CD-R write: 8X (maximum performance).
CD-ROM read: 32X (maximum performance).
