GSA-4163B DL Burner - Page 1
LG
Electronics, formerly known as GoldStar, was established in 1958 as
the pioneer in the Korean consumer electronics market. Since then, a
lot has changed in LG Electronics. In November 2000, Hitachi and LG
formed a new joint venture to manufacture optical storage drives
under the name "HL-DS". These recorders
are well tuned and with unique features.
After the successful GSA-4160B model, LG releases its latest DVD burner, the
GSA-4163B.
Below are the full specs for the drive:

Below are the drive's main specs as given by NeroInfoTool and DVDInfoPro:
The drive uses the well known RPC II region control, allowing a user to change the drive's region at most 5 times.
- The drive / Retail Package
The LG GSA-4163B retail package includes the internal SuperMulti GSA-4160B
burner, an IDE and an audio cable, four mounting screws, 2 CD-ROM discs and
the warranty. The first CD-ROM disc contains the user manual and the second
CD-ROM disc the bundled software which includes PowerDVD, PowerProducer Gold,
Nero Express, InCD and Acrobat reader. No blank media is included in the retail
package.
LG uses the same typical front panel available on most LG recorders. You can
see the "Super Multi", "DVD+RW", "US-RW" and "DVD
Multi Recorder" logos. However, there is still no DVD+R DL format logo.
On the rear you will find the analogue and digital audio outputs (SPDIF),
the IDE master/slave/cs selector pins, the IDE connector and the power input.
Opening the device's case will void the warranty, so we advise against it. Instead, use the photos in this review for a closer look under the hood. Clicking on the image below will reveal a high resolution image.
Below is a photo of the main chipset used for this drive:
- Installation
The device was connected in our test PC and was identified as "HL-DT-ST
DVDRAM GSA-4163B" under WinXP.
We received the drive with firmware version A100. We then
flashed the firmware to the latest release, version A102. All
writing tests in this review are made with firmware version A102.
In this review, we will be comparing the drive with the NEC ND3520A and Plextor
PX-716A since all three drives have been recently released and have similar
specifications.
- Testing software
In order to perform our tests we used:
- Nero CD-DVD Speed v3.61
- CDVD Benchmark v1.21
- ExactAudioCopy v0.9 beta5
- Nero Info Tool v2.27
- PlexTools v2.19a
- DVDInfoPro v3.16
- Nero Burning Rom v6.6.0.3
- DVD Decrypter 3.5.2.0
- CopyToDVD 3.0.42
2. Transfer Rate Reading Tests
LG GSA-4163B DL Burner - Page 2
Transfer Rate Reading Tests
- CD Format
According to each manufacturer's specifications, the LG has the slowest supported
reading speed for CD media and this is confirmed in our tests. With US-RW media
however, the LG and Plextor drives had similar performance with the NEC trailing
behind.
- DVD Format
Although speed differences are not significant, the LG GSA-4163B
performed very well being the fastest pressed Single Layer DVD-ROM reader.
The two layers of a PTP DVD-ROM disc are read sequentially with
the drive starting reading from the inner part of the disc, which is the beginning
of each layer, progressing towards the outer range for each layer. The LG was
slightly faster than the NEC drive but the Plextor PX-716A is way out in front...
The graph shown above indicates the reading performance of the
LG GSA-4163B with OTP dual layer media. The first layer of an OTP dual layer
DVD-ROM is read exactly the same way as the first layer of the PTP disc we tested
previously. The difference here is the reading strategy of the second layer
on the disc. The beginning of the second layer is located in the outer part
of the disc, so the drive starts reading from the outer tracks towards the inner
part of the disc. The LG once again was faster than the NEC but a good deal
slower than the Plextor.
The Plextor drive had the most stable reading speeds, hovering around 9X, across
the four formats, while the NEC drive was the fastest with DVD±R media
and slowest with DVD±RW media. The GSA-4163B also had fairly steady speeds
although on the slow side.
The LG drive performed well with a ripping speed of 9115kb/s, 6.6X. However,
the Plextor PX-716A is simply unbeatable in this task.
- DVD-RAM
The LG GSA-4163B can read DVD-RAM depending on the version of the inserted
media. For example, it reads 3X DVD-RAM (v2.1) media at 3X CLV, while 5X DVD-RAM
(v2.2) at 3~5 P-CAV, as the following Nero CD Speed graph shows:

CD Error Correction Tests
In the following tests we check the drive's behavior when reading
scratched / defective audio discs. The test discs used were the ABEX series
from ALMEDIO.

The total error count is very high, however the maximum error loudness is low
at -30.5dB and within acceptable levels. While there are quite a few muted samples,
there are no skipped samples thanks to the low error loudness level just mentioned.
The total test result score of 75.00 out of 100 is good.

The total error count is high but no samples were skipped. However, this is
a much easier test disk than the previous one and most drives pass this test
with a near perfect score. The total test result score of 82.7 out of 100 is
not as good as it could have been.
- CD-Check Audio Test Disc
The CD-Check Test Disc is a very useful tool for evaluating the Sound Reproduction
/ Error correction capabilities of a CD player. The disc offers a signal combination
with disc error patterns to rate the drive's abilities to read music and reproduce
it completely. Five tracks on the disc contain a sequence of progressively
more difficult tests. These tracks are referred to as Check Level-1 through
Check Level-5.
The
tracks are being reproduced through a software multimedia player (i.e.
Windows Media Player). Each level is considered as passed, if the tone
is smooth, continuous without interruptions, skipping or looping. The higher
the Check Level passed, the more reliable the sound reproduction
of the tested drive.

The drive successfully passed only the first two out of the five check levels
for this test. This is not good performance. Almost all drives have difficulties
reading the 5th level, while a good drive can read the 4th level. But almost
all drives can handle the third level defects without any problems. The performance
is similar to the previous LG model, the GSA-4160B.
- Summary
The CD error correction of the LG GSA-4163B, as was the case with the previous
LG GSA-4160B model, is mediocre.
4. DVD Error Correction Tests
LG
GSA-4163B DL Burner - Page 4
DVD Error Correction Tests
In the following tests, we examine the DVD reading capabilities of the drive
with scratched / defective DVD media. For the tests we used CDVD Benchmark
and Nero CDSpeed. The reference test media comes from ALMEDIO.
- Single Layer media
ABEX TDR-821
This is a single sided, single layer DVD-ROM with 4.7GB capacity, and its
surface has an artificial scratch of dimensions varying from 0.4 to 3.0 mm.
The following transfer rate picture comes from the CDVD Benchmark v1.21 transfer rate test.
The scratched area did not affect the reading process and no
errors were produced despite the high reading speed, which reached 16X towards
the end of the test.
ABEX TDR-825
This is also a single sided, single layer DVD-ROM of 4.7GB
capacity. The data structure of the disc is exactly the same as that of the
TDR-821, with the difference that there are no scratches on it but instead
defective areas of dimensions ranging from 0.5 to 1.1 mm.
There are also fingerprints sized between 65 and 75 micrometers.
Once again, the defective area did not affect the reading process.
- Dual Layer media
ABEX TDR-841
This is an 8.5GB dual layer, single sided DVD-ROM disc with artificial scratches
of dimensions ranging from 0.4 to 3.0mm, on both layers.
Excellent performance.
ABEX TDR-845
The disc is a single sided, dual layer DVD-ROM disc with a capacity of 8.5GB. The only difference between the TDR-845 and the TDR-841 is that the first includes defective areas and fingerprints. The dimensions of the defective areas range from 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micrometers.
Fantastic performance from the LG. The GSA-4163B carries on the reputation
of LG burners with DVD error correction.
ABEX TDV-541
The TDV-541 is a single sided, dual layer DVD-VIDEO disc, with a capacity
of 8.5GB. The disc is based on the TDV-540 series which is designed for inspection
and adjustment of DVD-VIDEO players. The disc checks the layer switch operation
from layer 0 to layer 1 and also includes test pictures and test signals for
DVD sound files.
The current TDV-541 also checks the error correcting capabilities of the
drive and includes scratches from 0.4 to 3.0 mm.
Although this test media is difficult for many drives, the LG read it without
any problems.
ABEX TDV-545
The TDV-545 disc is based on the TDV-540 series. It is a single sided, dual layer DVD-VIDEO disc with a capacity of 8.5GB.
The TDV-545 includes artificial black dots on the disc's surface, sized
from 0.4 to 1.0 mm. It also has 65 - 75 micrometer thickness, fingerprints.
Absolutely smooth curve, indicating good performance for this particular
test. The LG GSA-4163B has great DVD error correction capabilities.
5. Protected Disc Tests

Protected Disc Tests
- Reading Tests
To create the image of the various protected titles to the hard disk, we used Alcohol 120% software and the appropriate settings, according to the protection type of the inserted discs. Below you can see the duration of each process as well as the transfer rate in each case.
Game Title |
Protection Scheme |
Duration |
Reading speed |
PSX "NBA Jam Extreme" |
Lybcrypt |

5:02 min |
1111 sectors/sec |
VRally II |
SecuROM v.2 |
2:33 min |
2247 sectors/sec |
The performance for the LG GSA-4163B is similar, if not the same, with this of the LG GSA-4160B model.
The LG had fast performance with all the protections we tried. With PSX and
SecuROM protections, the drive was the fastest, while in the case of the Safedisc
protection scheme, it displayed performance that was better than most drives,
simply here, the Plextor drive has such a good tradition.
- Writing Tests
The drive supports the DAO-RAW writing mode. For checking the drive's
EFM correction status, we used 5 different game titles with different SafeDisc
2 versions having the latest software patches installed. After copying
the images of the various titles onto the hard disk, we burned them (maximum
speed)
with
Alcohol 120% v1.9.2.1705. Two different discs were created for each title;
one with the "Bypass EFM error" enabled and one more with the function
disabled.
- Fifa 2004 - Safe Disc v3.1x
- The Sims Superstar - Safe Disc v2.9x
- The Sims Unleashed - Safe Disc v2.8x
- Serious Sam Second Encounter - Safe Disc v2.51.021
- Max Payne - Safe Disc v2.51.020
The table below shows the results of the attempted backups and whether they worked (game installed / played normally), or not.

6. DAE Tests
LG
GSA-4163B DL Burner
- Page 6
DAE Tests
- Pressed and CDR AudioCD results
The drive supports up to 40X CAV DAE speed. The following results were reported when using Exact Audio Copy.
As it was expected, due to the supported speeds of each drive, the Plextor
was the fasted with LG and NEC following behind.
The drive also supports C2 error information.
- Advanced DAE Quality
Both the LG and Plextor received a perfect quality score of 100. The LG drive
can read Leadin data but not Leadout, and can also read CD Text and Subchannel
data. The reported average speed was 28.79X.
- Ripping 90mins AudioCDs
- Ripping 99mins AudioCDs
The drive can read/rip flawlessly both 90min and 99min Audio CDs, with no
speed fluctuations or drops. If you click on the images for the complete CDSpeed
graphs, you'll also see the low seek times which indicates how easily the drive
can read both discs. Not too many drives have shown this capability of late...
7. Protected AudioCDs
LG GSA-4163B DL Burner
- Page 7
Protected AudioCDs
For this test procedure we used three audio discs with different audio copy
protections. The ripping process on all protected Audio discs was carried out
with Exact Audio Copy v0.9beta5.
The sample protected Audio discs were:
- Sony's Key2Audio from "Celine Dion - New Day Has Come"
- Cactus Data Shield 200 from "Natalie Imbruglia - White Lilies Island"
The Cactus Data Shield 200, contains artificial errors that are not easily bypassed by the reader, while the Key2Audio contains a second session, causing problems for readers when trying to read the Table Of Contents (TOC).
The tested tasks are:
- Recognition of the inserted disc (Yes/No).
- Ripping all wavs (with EAC's Burst Mode) to the hard disk with copy&compare function.
- Listening to the produced wavs for any click/skips.
The LG drive recognized up to the 12th Audio track of CDS200 disc,
and with the "Retrieve Native TOC" option removed, the 13th Data
track was also recognized.
The test results are shown in the following table:
LG GSA-4163B |
Key2Audio |
CDS200 |
Ripping process completed, EAC reports no problems, Read&Test CRC comparison successful for all tracks |
Ripping process completed, EAC reports no problems, Read&Test CRC comparison not the same for all tracks |
With Key2Audio discs, EAC didn't report any timing
problems and at the same time, Read&Test CRC check comparison was the
same for corresponding tracks. The drive could not rip 100% accurately
the CD200 disc where Read&Test CRC check comparison was not the same
for corresponding tracks.
- Cactus Data Shield 200.0.4 - 3.0 build 16a (Aiko Katsukino - The Love Letter)
This is a "special" CDS200 build, since it doesn't contain any artificial errors during the ripping process. Most problems occur when trying to write the ripped wav files, since the produced CD-R disc contains C2 and CU errors! This "problem" is rumored to be connected with specific chipset weaknesses.
We ripped the disc contents with EAC and burned the wav file produced from the Cactus Data Shield 200.0.4 - 3.0 build 16a disc with the latest Nero version as AudioCD+CD-Text. The burned media was checked for C1/C2 errors and for BETA/Jitter errors with PlexTools software using Plextor PX-712S.
LG GSA-4163B |
CDS 200.0.4 - 3.0 build 16a |
Reading/Writing performed without any errors |
- C1C2 Error rate from PleXWriter PX-712A (8X CLV reading speed)
- BETA/Jitter Error rate from PleXWriter PX-712A
The C1/C2 error graphs show that the drive did not manage to produce a 100%
error free disc. However the C2 levels are low.
We then tried to extract all wav files with the Plextor PX-712A and PlexTools
DAE Error Correction 5th Level enabled:
No reading errors were reported after extracting all files.
8. CD Recording Tests
LG
GSA-4163B DL Burner
- Page 8
CD Recording Tests
- CD-R Format
The drive supports 4X, 8X, 16X (CLV), 24X, 32X and 40X (Z-CLV) writing speeds.
According to Nero CDSpeed, the drive reached a maximum speed of 40.48X
after 3.09 mins. The test started at 16.00X and had an average
speed of 31.76X.
- CD-R Recording Times
We created an 80min data compilation with Nero Burning Rom
and recorded it on a 700MB disc. The writing performance varies according
to the inserted media. Below is a chart demonstrating all recording times
with various media.
Once again, due to the different supported speeds, for CD writing this time,
the Plextor was the fastest while the NEC and LG drives followed.
- Other features
The LG GSA-4163B supports overburning, writing up to 95mins and can read/write CD-Text.
- CD-RW Format
The drive supports both the HS-RW and US-RW formats. With US-RW media, 16X
(CLV) and 24X (Z-CLV) writing speeds are available.
Below you can see the Nero
CD-DVD Speed writing simulation test with blank 24X US-RW media from Mitsubishi
Chemicals.
According to Nero CDSpeed, the drive reached a maximum of 24.02X writing speed. The test started at 16.00X, having an average speed of 23.30X. The time needed for this task was 3:36min.
- CD-RW Mount Rainier
The drive doesn't support the Mount Rainier feature.
9. Writing Quality Tests - Clover System Tests
LG
GSA-4163B DL Burner

Writing Quality Tests - Clover System Tests
The Clover Systems CDX Compact Disc Analyzer is a high-speed tool to quantitatively measure the quality of a CD. It will analyze CD-DA, CD-ROM, CD-ROM XA, CD-I, CD-R, Photo-CD, Enhanced CD and CD-RW discs at 4X, 8X, 24X, 32X or 40X speed. It effectively measures disc quality by examining the quantity and severity of CIRC errors generated during playback. It also provides the capability to measure signal parameters related to pit geometry, such as asymmetry and reflectivity. Together, all these bits of information provide a thorough analysis of disc quality. The Clover Systems Analyzers can also perform various format-checking tests on data discs, and do bit-for-bit data comparison on all types of CDs. All tests are carried out at the maximum speed of 40X.
CIRC error correction uses two principles to detect and correct errors. The first is redundancy (extra information is added, which gives an extra chance to read the disc), and the second is interleaving (data is distributed over a relatively large physical area). The CIRC error correction used in CD players uses two stages of error correction, the well known C1 and C2, with de-interleaving of the data between the stages.
The error type E11 means one bad symbol was corrected in the C1 stage. E21means two bad symbols were corrected in the C1 stage. E31 means that there were three or more bad symbols at the C1 stage. This block is uncorrectable at the C1 stage, and is passed to the C2 stage. Respectively, E12 means one bad symbol was corrected in the C2 stage and E22 means two bad symbols were corrected in the C2 stage. E32 means that there were three or more bad symbols in one block at the C2 stage, and therefore this error is not correctable.
BLER (Block Error Rate) is defined as the number of data blocks per second that contain detectable errors, at the input of the C1 decoder. Since this is the most general measurement of the quality of a disc, you will find BLER graphs for all media tested below. If you click on the images you can see a more detailed table, indicating error levels. The Red Book specification (IEC 908) calls for a maximum BLER of 220 per second averaged over ten seconds. Discs with higher BLER are likely to produce uncorrectable errors. Al low BLER shows that the system as a whole is performing well, and the pit geometry is good. However, BLER only tells us how many errors were generated per second, and it does not tell us anything about the severity of those errors.
- Summary
Taiyo Yuden, MMore and BenQ media reported good writing quality without E32
errors being reported. We would like the performance with the two other media
brands to be fixed in a future firmware revision.

10. DVD Recording Tests
LG
GSA-4163B DL Burner
- Page 10
DVD Recording Tests
- Writing Performance
The LG GSA-4163B supports DVD-R/RW, DVD+R/RW and DVD-RAM writing.
The maximum supported speeds are 16X P-CAV for DVD+R and DVD-R, 8X Z-CLV
for DVD+RW, 6X CLV for DVD-RW, 4X CLV for
DVD+R9 and
5X P-CAV for DVD-RAM media. Notice that the difference between
the LG GSA-4163B and the previous LG GSA-4160B models are not only in maximum
supported speeds but also in writing strategies.
Nero Burning Rom reported speeds are shown below, after inserting a DVD+R
16X certified disc.
Note that when the software identifies a disc as 8X or higher, the 2X or the 2,4X writing
speed option, for DVD-R and DVD+R respectively, is not available. However, if the maximum speed is
4X,
2X
or 2.4X writing
speed
is available.
By using Nero CD-DVD Speed with DVD-R and DVD+R media, we are able to see
the supported writing strategy for each speed and format for this burner. Click
on each image below for a complete CDSpeed graph.
According to the graph above, the writing strategy is P-CAV, and not CAV as
is the case for most drives, where the 16X speed is reached relatively early
and remains for approximately 800MB. Furthermore, the test started at a speed
of 7.28X and for those two reasons, the LG drive proved to be the fastest
16X
DVD+R recorder.
For 12X, the writing strategy is Z-CLV.
As with the DVD+R format, the same is happening here with DVD-R. For the same
two reasons we mentioned above, the drive is also the fastest with DVD-R.
The drive reaches the maximum 8X speed too early and kept it until the end of the burning process.
6X CLV for the DVD-RW format. Not bad...
- Burning Tests
We burned 4315MB of data on various DVD±R, DVD±RW media. We used the maximum allowed writing speed for each disc.
The reported writing time 5:17min at 16X is the slowest we ever experience.
The excusion for this is the writing strategy we mentioned above. Notice how
stable is the performance, almost the same times for each recording speed.
As we have already mentioned a few times, we will say it again that the drive
is the fastest 16X burner. Once again, stable performance.
- Comparison with other drives
No matter what the format is, the LG GSA-4163B is unbeatable...
- DVD Overburning Tests
Using Nero CD-DVD Speed, we tested to see if the drive can overburn using
DVD+R and DVD-R media. Unfortunately, the drive does not support overburning,
giving
the following error with all inserted media.
- DVD+MRW Tests
The drive doesn't support the Mount Rainier feature.
11. CDSpeed/PlexTools Scans - Page 1
LG
GSA-4163B DL Burner
- Page 11
CDSpeed/PlexTools Scans - Page 1
In order to test the writing quality and readability of the burned media we used two readers with two software applications:
- The LiteON SOHD-167T with patched firmware being able to read DVD5 up to 16X CAV and DVD9 up to 10X CAV. For the transfer rate tests we used the latest Nero CDSpeed version.
- The Plextor PX-712A with the latest available firmware. For scanning the disc, we used the latest PlexTools version at 2X CLV reading speed, BURST mode, with middle accuracy.
In general, a "perfect" disc should have a smooth reading curve, very low PIE/POE and zero (0) POF error rates. Most times however, even though a disc has very low PIE/POE error rates, the reading curve may not be smooth containing dropoffs. Due to the fact that we oversped the reading capabilities of the LiteON SOHD-167T, such drops are expected, especially near the outer area of the disc.
The measurements below should be taken not as the absolute criteria of the burning quality, but as an indication level.
16X DVD-R Writing Speed
- Mitsubishi Chemicals 16X DVD-R @ 16X
- Summary
Since both media were burned at 5:17min we expected higher PIE values. However,
these were low while the CDSpeed graph for Mitsubishi Chemicals media was smooth.
In the case of TDK media, the speed started to slow down at the outer area but
even in this case, the quality was more than good.

- The Plextor PX-712A with the latest available firmware. For scanning the disc, we used the latest PlexTools version at 2X CLV reading speed, BURST mode, with middle accuracy.
In general, a "perfect" disc should have a smooth reading curve, very low PIE/POE and zero (0) POF error rates. Most times however, even though a disc has very low PIE/POE error rates, the reading curve may not be smooth containing dropoffs. Due to the fact that we oversped the reading capabilities of the LiteON SOHD-167T, such drops are expected, especially near the outer area of the disc.
The measurements below should be taken not as the absolute criteria of the burning quality, but as an indication level.
8X DVD-R Writing Speed
- Datawrite ( TTG02) 8X DVD-R @ 8X
- DataWrite ( CMC MAG AE1) 8X DVD-R @ 8X
- Mitsubishi Chemicals 8X DVD-R @ 8X
- Summary
In all cases the quality was very good. Only with the Maxell disc, the PIE
values were a little increased but even this cannot detract from the excellent
recording quality of the drive.

12X DVD+R Writing Speed
- Summary
Quality for 12X is higher than 16X, which is logical. There were a few cases
with increased PIE values but only in one was it over the limit. Once again,
the quality is good.

Writing Quality Tests - Almedio AEC-1000
The AEC-1000 consists of a DVD Drive and the "ALChecker" error measurement
application which can check the written data quality. The application is capable
of 1X CLV measurement as well as 4X CLV on DVD-Video/ROM and finalized DVD+R/-R
media. There are three measurement modes, Fine Mode, Rough Mode and Quick Mode.
The first checks a series of eight consecutive ECC blocks, the second checks
eight consecutive ECC blocks every 100h ECC blocks and the last, the fastest,
checks three specified areas. The checking status is shown graphically in real
time while you can save the error graph at the end of the test. The reported
errors are the PI and the UncPO. In the case of PI, it counts the number of
rows corrected by the PI error correction in each group of eight consecutive
ECC blocks. In the case of UncPO, it counts the number of ECC blocks in which
more than one byte is uncorrectable in eight consecutive ECC blocks. For our
quality scans, we set for 1X CLV and Fine Mode which is the slowest and with
the safest results. Also, we chose to measure all the media burned at the maximum
available writing speed, namely 16X.
- Mitsubishi Chemicals DVD-R 16X @ 16X
- Mitsubishi Chemicals DVD+R 16X @ 16X
- Summary
The DVD+R media was burned with booktype DVD-ROM. For this reason, the ID codes
of these media is not available in the above tables.

- Writing Tests
The LG GSA-4163B model supports Double Layer media. It can
record this type of media at 4X. We burned five different DL media from Verbatim,
Traxdata, Philips, Ricoh and CMC Magnetics with DVD-Video content. The source
disc was "Gladiator Movie - Special Edition" Disc1 with a
total size of 6.86GB.
First, we transferred the movie to the hard disc with DVD Decrypter in
ISO format (single file). We used the latest version of CopyToDVD software
to burn
the image file to all media. We chose
the "GLADIATOR.ISO" image and we
selected the LG burner to start burning.
The recorder needed sometime to initialize the inserted media and the recording
process started after approximately 30 seconds. Below are the log files for
each media we used:
For comparison reasons, we post some burning results from other DL writers,
which all burned the same content ("Gladiator Movie - Special Edition" disc1),
using the CopyToDVD software:

22. DVD-RAM Tests

DVD-RAM Tests
The LG recorders are the first ever PC recorders to support 5X DVD-RAM media.
Maxell announced on 26th of May, 2004, the release of 5X DVD-RAM media. DVD-RAM
media is the most appropriate media for large file storage and recovery, since
it combines an error correction system and BCM (Bismuth Coupling Material) recording
layer technology, which improves signal to noise ratio for higher reliability
during high-speed recording.
As Maxell stated: "DVD-RAM is an advanced recording media format that offers a range of digital data applications. Its phase-change recording material allows discs to be re-recordable and erasable, and a superior defect management system ensures accurate recording and playback. DVD-RAM allows instant, random access to any location on the disc for fast and easy data reading and writing. Because DVD-RAM supports fast formatting and no finalizing, it is an extremely easy-to-use media. And with DVD-RAM, changes can be made directly on the disc without the need to transfer data to a hard drive first, speeding up the editing tasks..."
For our test, we used two different DVD-RAM media, Optodisc 3X DVD-RAM media
and Maxell 5X DVD-RAM media. Below, you can see the media information according
to DVDInfoPro:
You can see that the Optodisc media comes pre-formatted with UDF2.00, meaning
WinXP/2k will recognize the disc directly, since DVD-RAM is supported by Microsoft.
Of course, you can format (erase) the disc and use it with a normal application
like Nero. LG includes the well known InCD for packet writing.
For our tests, we used the latest InCD version 4.3.11.1:
After installing InCD, a new TAB was added to the drive's properties providing
information about the media file system:
Since the Maxell media was not formatted, we used InCD for this.
Then we were able to copy files from the HD onto the DVD-RAM media, using the
drag'n'drop method, as well as delete them.
- Burning Tests
Using NeroCDSpeed, we got the following graph:
The drive started writing at 1.39X using the P-CAV
writing strategy and reached 2.35X, giving an average writing
speed of 2.15X. To find an explanation as to why the drive
cannot reach 5X writing speed, we need to look at writing strategies. The LG
drive uses the "write and verify" function while writing to DVD-RAM
media, as opposed to +R/+RW or -R/-RW media, where the verify function is not
used. Hence, with DVD-RAM media, the drive automatically verifies all written
data. This explains why the drive reports or implies a slower speed than the
specifications give.
LG commented that "...In the case of DVD-RAM, it has Write and Verify
feature. This means drive reads after write to verify written data. Default
setting of GSA-4163B for this Write and Verify feature is enabled. This
is the reason why you see ~1.4-2.1X writing speed, which is just below half
of 5X speed. In the case of video streaming data write, Write and Verify
feature is disabled, therefore, in this case writing speed is 5X ZCLV..."
Using the latest Nero version, we burned our usual Single Layer DVD complilation.
- Optodisc 3X DVD-RAM media
We hope to see better recording times in the near future, or at least the choice
to select between "write and verify" or simply "write" with
DVD-RAM media.
23. BookType Setting

BookType Setting
We used several software applications to investigate booktype setting support
for this recorder. Unfortunately, the drive supports this feature but only for
DVD+R and DVD+R DL. We would like to see the same for the DVD+RW format.
24. Conclusion

Conclusion
The GSA-4163B model replaced the existing, very good GSA-4160B burner. The
new drive not only rose to the occasion, reaching the maximum writing speeds
for the DVD-R, DVD-RW, DVD+RW and DVD+R DL formats but also changed the writing
strategy for the DVD+R. This results in even lower recording times. The reported
recording times during our tests for all the formats, place the GSA-4163B in
first place among all the burners currently available on the market with 5:17min,
5:20min, 9:46min and 7:15min for the DVD-R, DVD+R, DVD-RW and DVD+RW respectively.
LG models are known for their good reading ability, and the new model confirmed
this for one more time. The drive managed to read all the media we used, defective
or not, even 90/99min CD media which prove troublesome for the latest burners.
The error correction is very good for the DVD format but with the CD format
needs further improvement. This performance is similar, if not the same, as
the previous GSA-4160B model.
The CD/DVD ripping speed is good but not the fastest we have ever seen. With
copy protected games, the speed was very high, no matter what the protection
scheme, while the drive also managed to rip/play successfully all the copy protected
AudioCDs we tried. We would also like to see better behavior from the drive
when it comes to backing up SafeDisc protected games. In this task, the performance
was average and the drive managed to create working backups up to v2.8. To be
honest, we really didn't expect anything better since this has now become common
issue with the latest DVD burners.
As far as writing quality of the GSA-4163B is concerned, this proved to be very
good. With all the DVD formats, the reported PIE levels were rather low while
in most cases this was also confirmed by CDSpeed. In very few cases, the levels
were high but this does not affect the overall good image of the drive. With
CD media, the quality was also good with most of the brands we tried. Further
improvements in this area would be welcome though.
Fortunately, LG has decided to support the booktype change feature for this
burner, as it also does with the GSA-4120B. DVD+R and DVD+R DL can be easily
set to DVD-ROM booktype with CDSpeed, DVD Decrypter or even straight from Neo
Burning Rom. We would like the DVD+RW to support the same feature as well as
the GSA-4160B :-)
DVD-RAM support, at 5X max, is another advantage with this drive which can
automatically verify all written data, (a function that will reduce the effective
writing speed), offering the highest reliability among DVD re-writable media
with 100,000 re-write times and superior defect management.
Finally, the burner is already available on the market at approximately $77,
at the time of this review. The price is very good if we keep in mind that other
burners with similar specifications cost around $100 or even more.
