ELI5: When burning a CD, does a 4x vs a 1x write speed change the quality of the end product? Is there anything different about a 4x vs any other speed other than, speed?

I always thought this harkened back to the old days of CD burning, where buffer underruns occurred frequently.  A buffer was created for the data being burned, and if the buffer emptied before the burning process is complete, it would fail.

  Burning at a slower speed (1x) meant you didn't empty the buffer and cause problems. However if your PC could handle it, you could attempt to burn at faster speeds (4x).
