CDFreaks take a look at the GSA-4166B Super Multi DVD-Writer with LightScribe that produce precise, laser-etched labels. This drive supports 16x DVD+R/-R, 8x/6x DVD+RW/-RW, 5x DVD-RAM, 8x/4x DVD+R DL/-R DL writing and with the LightScribe thrown in on top, you also have direct disc labeling.

LG's offering with the GSA-4166B performs with good to excellent write quality on just about every media type tested with a few exceptions. The drives support for DVD-RAM and LightScribe Direct to Disc Labeling technology truly makes this drive a 'Super Multi Drive'. Bitsetting on DVD+R/+R DL is supported by default and ensures good compatibility with set top DVD players.  LG has included a software bundle with this drive that will have nearly every 'DVD' need covered for a beginning user as well as some of the more sophisticated needs of the more advanced user.

There are few negatives to mention. The LG GSA-4166B does not offer over speed support with the exception of some DVD+R DL MIDs. Overburning support on CD-R is lacking, it also lacks bitsetting support on DVD+RW media and does not provide disc PI/PIF error scanning.
