LG-GH22NS30 22x

1. Features, specifications

It may be less than a month before the first 24x reach the market of DVD burners, but today we are having a look at LG's latest solution for 22x DVD recording, the GH22NS30. This drive is a Super-Multi DVD writer, supporting all DVD media currently available. The drive we got is a bulk version meaning that it comes with no software or any other goodies found in the retail packages of other drives. But still, it would be interesting to see how fast and reliably this baby performs, compared to other 22x DVD burners from LiteOn and Samsung.

In detail, the LG drive is able to burn DVD±R media at 22X, DVD+R DL at 16X, DVD-R/+R DL at 16X, DVD+RW media at 8X, DVD-RW at 6X and DVD-RAM at 12X. It is connected to the computer via a S-ATA interface, thus allowing Burst Transfer Rates of up to 1.5Gbps.

The drive's key features are:

- Drive Specifications

LG hasn't changed much on the front faceplate of the drive, which is also met at the company's previous models. The "SuperMulti" and "SecurDisc" logos are there, although the CD and DVD+R/+RW logos are missing.

At the rear side we find the typical SATA and power connectors.

The GH22NS30 by HL Data Storage was manufactured in November 2008.

The internal board of the drive is rather small, as you can see below.

The GH22NS30 uses Panasonic's MN103SD9GRAB chip. The company also uses chipsets from Renesas in other 22x DVD models.


- Installation

The drive was identified under Windows XP as "HL-DT-ST DVD-RAM GH22NS30", firmware version 1.01.

2. CD / DVD read tests

For our CD transfer rate tests, we used the Nero Disc Speed utility and a set of data and audio CD-R/RW/ROM. The drive can read CD media at a maximum speed of 48X.

For each CDSpeed graph, you can click on the image to see the complete screenshot, including full measurements.



The following CD Speed graph shows the reading performance with US-RW media. Reading reached a maximum of 40x, as per the specifications.


- AudioCD

In the CD Speed Advanced DAE quality test, the drive's average speed was 28.54X with a quality score of 100.

A typical DAE task with an 80min non-protected Audio CD produced 28.8X average ripping speed.

DVD Format

Now let's take a look at how the drive performs with DVD media. This time, a set of SL and DL DVD media was used. The drive is capable of reading at 16X maximum speed for single layer DVD ROM and at 12X for dual layer DVD ROM media.

DVD-ROM SL media -



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 its outer range.


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 of 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 and progresses towards the inner part of the disc.














-DVD RAM (2-5x media)

-DVD RAM (12x media)



Huge reading problems here with the Maxell 12x DVD-RAM disc.

- DVD Video Ripping

Ripping of a single layer DVD movie:

Average 11,855 kB/s (8.6X)
Maximum 16,787 kB/s (12.1X)

- Summary of reading tests

The drive was quick enough with all the CD and DVD discs and reading was accurate. However, the 12x DVD-RAM disc caused significant problems and it seems that the some exrta work is needed here to make the HG22NS30 read the specific disc.

3. CD error correction tests

This series of tests checks the drive's ability to correct/conceal possible erroneous data after reading artificially scratched / defective audio discs. The test discs used were the ABEX series from ALMEDIO.

Specifically, a software compares two audio files using FFT analysis. The first audio file has been extracted by a normal audio disc. The second one is the result of the extraction of the another disc which hold the same audio track, but it also has specific defects on its surface. The similarity factor of the the two tracks unveils the error correction capabilities of the drive.

The differences between the two compared tracks are translated to a signal (noise) illustrated in the following graphs. We should note here that this signal is normally appearing here, since there is not any drive capable of fully correcting the serious errors reported for these test discs.


Errors total Num : 1003189
Errors (Loudness) 55721 Avg:-74.4 dB(A) Max :-20.1 dB(A)
Error Muting Num : 3212 Avg : 1.0 Samples Max : 8 Samples
Skips Num : 0 Avg : 0.0 Samples Max : 0 Samples
Total Test Result 76.7 points (of 100.0 maximum)

An adequate score for the LG drive here. There were no skipped samples and the error correction did not start earlier than it should and the Error Loudness sometimes surpassed the -60 dB(A) border. Noise above that value can sometimes become audible, depending on the music that surrounds it.

- ABEX TCD-726

Errors total Num : 0
Errors (Loudness) Num : 0 Avg : -174.0 dB(A) Max : -174.0 dB(A)
Error Muting Num : 0 Avg : 0.0 Samples Max : 0 Samples
Skips Num : 0 Avg : 0.0 Samples Max : 0 Samples
Total Test Result 100.0 points (of 100.0 maximum)

Pretty good performance here for the error correction mechanisms.

- CD-Check Audio Test Disc

The CD-Check Test Disc is another 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 reproduced through a software multimedia player (e.g. 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.

Error Level 1 2 3 4 5
LG GH22NS30 5/5 5/5 5/5 0/5 0/5

Playback of the majority of the last two tracks (4 and 5) produced audible noise and interruptions. This is a common score among DVD-RW drives and shows acceptable error correction mechanisms.

4. DVD error correction tests

In the following tests, we examine the DVD reading capabilities of the drive (error correction) 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


This is a single sided, single layer DVD-ROM with a 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.

Flawless reading, without any problems and without dropping speed.


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.



The drive managed to read the disc successfully, without any read errors.

- Dual Layer media


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.



A good read by the drive here, producing a smooth graph.


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 reading process produced a read error here, as the drive was unable to read the disc at a point near the start of the second layer.


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 data surface, sized from 0.4 to 1.0 mm. It also has 65 - 75 micrometer fingerprints.


Flawless reading here, producing a smooth and symmetrical speed graph.


Overall, the DVD error correction mechanisms are generally good.

5. Test platform - The IQB Omni CD DVD Analyser by Quantized

All CD/DVD writing quality tests are done using the IQB Omni CD DVD Analyser by Quantized. The IQB Omni from Quantized Systems is a physical disc analyser, covering all CD and DVD formats, designed to meet the Quality Control demands of the duplication and replication sectors.

Omni's features allows you to identify media quality issues and highlight drive performance and recording problems.

The system is based on a Philips CD/DVD drive. It supports the majority of the optical disc formats, including CD-ROM, CD-R/RW, CD-A

The platform can test the media for the following signals:

Reflectivity R-I14H R-I14H R-I14H
Jitter Modulation Modulation Modulation
I11/ITop Jitter Jitter Jitter
Asymmetry/Beta PI Sum 8 PI Sum 8 PI SUm 8
E11 to E32 Error Statistics POF POF POF
Burst Errors Beta Beta Asymmetry
  ADER Unc    

Test speeds for CD media are set at 16X and for DVD media at 4X.

The equipment is capable of providing measurements on the complete data area or at specific positions defined by the user (Quick Test mode). This zone testing procedure allows multiple areas of the disc to be tested in a single operation.

All numerical and graphical data are stored in a database. Data can be recalled with user defined criteria to create sets of related key results. Data can also be imported into most common software packages - MS Excel etc.

For more information on the Quantized IQB Omni Analyser, visit http://www.quantized.com.

In the following pages, we present the writing quality measurements of various CD and DVD recordable and rewritable media, burned with the LG GH22NS30 DVD burner.

As we can see, the drive does not support overburning of DVD recordable media, according to Nero Disc Speed.

29. Final words

Let's summarize the results of all the tests that we performed on the LG GH22NS30 drive.

To start with the reading aspect of the drive, we have to say that it turned out to be pretty good, with the drive reading all discs at speeds according to its specifications. Most reading processes were nice producing smooth graphs. As far as error correction is concerned, we can say that the drive can handle DVD defective media pretty well. However, it could be better on the error correction tests with CDs, although nor the Samsung 22x burner nor LiteOn's 22x solution had performed better in this test.

Next on, are the writing tests that we performed. The burning speed was very good, successfully burning at 22x more media than any other burner currently available. It also successfully burned all media according to specifications, leaving us no choice, but to be satisfied.

However, writing quality was a mixed bag. The tests on most of the burned discs reported many uncorrectable digital errors. These errors were at many times way over limit, thus making the burns not satisfactory. On the bright side, though, there were some discs that were burned flawlessly, and one among them is the MCC 03RG20 disc, which was burned at 22X. Most of these issues could be addressed through optimizations of the writing strategy the drive uses with each different disc. By the time these lines were written, LG released a new version (v1.02) for the drive. We are not sure that the new firmware actually improves the writing performance of the drive but flashing your drive is always recommended.

We also liked that the DVD+RW/-RW discs we tested were in perfect shape, as well as the DVD+R DL discs. Some errors were reported with the DVD-R DL samples we tested. The CD writing quality at the highest speed of 48x was pretty high.

We should also note here that the LG GH22NS30 had hard times reading the Maxell 12x DVD-RAM disc. The SecurDisc feature feature is also available if you like to play around with passwords and protect your discs, while the supported Bit Setting ensures the compatibility of your DVD+R/+R DL discs.

To sum up, the drive has the potential to become the the best choice for 22X burning after some extra optimizations that could fix some writing quality issues. The drive can be bought for about $70.
