For your information, the fastest CD burning speed with an excellent reliability rating is 8x. The most acceptable CD burning speed with a very good reliability rate is 12x. Burning 16x is a hit and miss scenario leaning on the successful burning result but I do not generally recommend this. Note that *virtually* walang pakialam dito ang CPU speed and available CPU RAM, although the IMAPI driver engine would
sometimes need CPU resources for packet reading, writing and verification. Also, if you burn in 8x, you can still safely multi-task without the fear of getting a mis-burnt CD via buffer overruns or underruns.

There are mainly three types of recording dyes used in CD media - cyanine, phthalocyanine and AZO. Although you can super heat them at high speeds, the resulting superheated distortion of the recording dyes provide more reliable data-consistency at slower burning speeds.
