IMO, not very well. I use an USB external plextor drive to Rip...
all things equal (computer, settings, drives, cd, etc) Itunes rips cd's
extremely fast, almost... uncomfortably fast. One time I put a disc
in and went to grab my pizza from the oven; by the time I came
back, all 16 tracks had ripped. That always made me uncomfortable.
God forbid any scratches on the Cd... itunes makes no effort to correct
these.
using the same system, I now rip with EAC and receive far better results.
EAC takes its time, always results in an accurate, great sounding file.
I convert the file to Apple lossless after so I can use it in my ipod.
