The specifications of the LG GSA-4163B state that the drive is able to write CD-R discs at 40x and CD-RW at 24x. Let us find out how the drive really performs in speed and quality.
Writing Data CD-R discs:
For our data writing tests, we simply set up a new compilation of 700Mb using Nero Burning ROM software. Writing method used is DAO (Disc At Once), and the disc is set up as a non-multisession disc with 'finalize disc" enabled. The screenshot below shows how long it takes to write a disc at the highest speed. (40x):

The drive used 3 minutes and 15 seconds to write the disc at 40x. (Actually write speed 40.5x). Let us see how this compares to other drives:
- Philips DVDR1640P used 3 minutes and 17 seconds at 40x
- NU DDW-082 used 3 minutes and 2 seconds at 40x
- Samsung TS-H552B used exactly 3 minutes at 40x
- Plextor PX-708A used 2 minutes and 58 seconds at 40x
Write Quality:
We will test CD-R discs from a total of 6 different CD-R manufacturers. To really measure the write speed, we used the 'create data CD" function in Nero CD-Speed. The discs were written at the maximum speed that the drive supports. For the quality test, we used K-Probe 2 which is a tool developed by a Lite-On Employee. It runs under Windows and works with drives made by Lite-On. Also note that different drives and different reading speeds may affect the results obtained when scanning the discs. We used a Lite-On SOHR-5238S drive with firmware 4S06 and scanned the discs at 48X speed.
A written CD-R disc will always have some C1 errors; C1 errors are easily corrected by the drive's error correction capabilities. The next level of errors is C2, while C2 errors could also be corrected by most drive's error correction capabilities; they are not wanted on a good quality disc. A good disc should not contain any C2 errors, and preferably have an average C1 error amount of below 2.0 for the best discs, or at least below 10.0 averages for good quality discs. After C2 errors there are only un-correctable errors that will make a disc unusable.
Why wait any longer? Below are the obtained results:

Writing Quality with Re-Writable discs:
Due to requests from our readers, we will add a few write quality tests with Re-Writable media. Settings and testing procedures is the same as used earlier in this review, so you may want to go back and read them if unsure. All discs used for these tests have been written to before, but none have been written to more than 5 times.

We can see some high spikes in the beginning of the disc, but nothing serious. A good result!

Once again, some high spikes in the beginning of the disc, but a good result.
Summary:
The results are just
excellent! Overall, it does a fantastic job writing to CD-R Media.
So let us head on to next page and read about DVD-Writing performance…

Is this the new No.1??? and the Benq 1620 goes to 2nd place??


Though it does not completely eclipse BenQ because it does not support +RW bitsetting.


The BenQ on the other hand has much better media compatibility and overspeeding abilities along with great quality as well. + it has pretty good media testing abilities.
But you will not go wrong with any of these drives - but remember, the LG is brand new, and we hope benQ and other manufacturers has something new in their pockets soon as well......


The drive is very nice though. The added support of dvd-r dl would be sweet.


Cheers, Mookie













I purchased this drive and sold it back 6 hours later because of that. The digital-like connector on the rear side is labeled "Reserved". The connector is simply unconnected inside the drive.
Ough, back on the beginning. I have to read reviews again in order to find another one with similar pros / cons, which hopefully has SPDIF output physically present (and similar or up to 30% more price).

Thats the best way really anyways.
