For a CD-ROM player or CD recorder, a "1x" speed translates to 153,600 bytes per second. This is usually rounded down to 150 kb per second. Therefore, a "1x" recorder writes 150 kb per second to the CD-R media. Likewise, a "2x" recorder writes at 300 kb per second, a "4x" records at 600 kb per second, a "8x" records at 1200 kb per second, a "12x" records at 1800 kb per second and a "16x" records at 2400 kb per second. Note that there are some variations in measuring speed because there are recording modes that provide more than 2048 data bytes per frame (audio is recorded at 2352 bytes per frame).
