Is lg 4163 a fast reader and a fast ripper?

is lg 4163 a fast reader and a fast ripper?
what is the reading speed of lg 4163?
what medi ais it good with?
how are burns made with +R and -R?
are they about equal in quality?

It is relative.

The LG 4163 is a much slower reader than my NEC 3500, and a much slower ripper compared to my Pioneer 109.

However, it is a fast burner, both with 16x -R and +R. It will overspeed some 8x +R to 12x. Quality is similar.

If you need qood quality and reliability you should buy it.
The wonderfull, is that it writes almost everything, both -R and +R.
As for ripping and reading is not the fastest drive.
But I will hardly exchange it for another, at least for the moment.
