Summary: For single-layer 4.7GB formats, this drive is superb, producing some stunning times. It's also very well-priced and, for these reasons, should be a hit. However, those who are more interested in using 8.5GB double-layer formats will find better deals elsewhere.
Pros: DVD-RAM Support, Great variety of formats, Fairly quick
Conclusion: The already excellent GSA-4163B has been replaced by the GSA-4167B. So it would be rather interesting to see what is new from LG. Firstly, the supported writing speeds have been increased, allowing LG to compete against other manufacturers.
