Model: LG GGC-H20L Super Multi Blue Blu-ray Disc & HD DVD-ROM
Manufacturer: LG Electronics
Provided By: LG Electronics USA
LG Electronics has been a leader in the industry for nearly 50 years. Since the introduction of their first radio in 1959, the company has grown to become one of the world's top electronics manufacturers, offering everything from large home appliances to tiny mobile phones. LG is no stranger to the optical storage industry either. Working closely with companies like Hitachi, they've lead the way in this area, developing and manufacturing a wide range of products, including the industry's first "Super-Multi" drives.
To make it easier for consumers to go high-def, LG has introduced a series of "Super Multi Blue" drives that support both Blu-ray and HD DVD. This winter, LG launched their second generation of Super Multi Blue drives. Along with the GGW-H20L, the company introduced a more affordable, read only model, the GGC-H20L. While lacking BD writing capabilities, the drive sports specs very similar to the GGW-H20L. The GGC-H20L is capable of 16x DVD±R, 8x DVD+RW, 6x DVD-RW, 4x DVD±R DL and 5x DVD-RAM writing speeds and a maximum DVD read speed of 16x. On top of that, it can read HD DVD's at 3x and Blu-ray Discs at speeds as high as 6x. The GGC-H20L also includes features like a 4MB buffer, support for HP's LightScribe Direct Disc Labeling system and a software bundle from CyberLink.
We've had LG's new Super Multi Blue drive in the 'Labs for a few months now and have had the time to put it through its paces. To give you an idea of what to expect from the GGC-H20L, we'll take a look at some of its features and then see how it compares to some of the Blu-ray Disc drives from the competition. Does the GGC-H20L have what it takes? More importantly, it the best bang for your buck? Keep reading to find out.
The GGC-H20L LG sent us was an early production sample. While the drive came in a retail box with the bundled software burned onto a CD-R disc, it did not include a printed manual or any cables.
Physical Features:
The drive LG sent us for this review was manufactured in July of 2007 and had firmware version 1.00. For this review we used firmware versions 1.00 and 1.02.
From the front, the GGC-H20L looks a lot like LG's original Super Multi Blue drive, the GGC-H10N. While there are a few cosmetic differences, like the placement of the LED and emergency hole, it shares the same basic design and has many of the same logos. Along with the large "Super Multi Blue" and "LG" logos, you can see a few showing support for Blu-ray Disc and HD DVD as well as HP's LightScribe technology.
Below the tray you can see the GGC-H20L's single LED. Off by default, this LED lights up a bright blue whenever the drive is reading or writing.
The rear of the GGC-H20L is pretty straightforward. By looking at the picture above you can see the drive's SATA interface and power connector.

LightScribe:
Note: We took a much closer look at LightScribe technology in our review of the BenQ DW1625. In this review we'll just go over some of the basics and see how the GGC-H20L performs with the bundled software.
The GGC-H20L is one of the first Blu-ray Disc writers to feature LightScribe technology. Developed by HP, LightScribe lets you burn durable, silk screen quality labels directly onto your CD's and DVD's using the same drive that burned the data. According to HP, it's as simple as burning the data, flipping the disc, and then burning the label.
Of course you can't do this with just any drive, media or software. While LightScribe capable drives use the same laser when burning both the data and label, they have to be able to accurately control the laser's focus and position as well as the spindle speed. They also must be able to recognize LightScribe media. These special discs have a thin dye coating on the label side that absorbs laser light. This triggers a chemical reaction that produces a color change, allowing the user to print text, artwork or graphics.
Even if you have a LightScribe capable drive and media, you will need software that supports it. Most major software companies have pledged support for the technology. However, at the time of this review, the list of compatible software is still relatively short. For the GGC-H20L, LG turned to CyberLink. Using the bundled LabelPrint software you can create and burn LightScribe disc labels.
Once you've created your LightScribe label, you're ready to print it. Before you can do this though, you will need to choose the contrast. Keep in mind this option not only changes the level of detail, it also affects the amount of time it takes to print the label. The higher the quality, the longer the process will take.
How long does it take to print a label? For testing purposes, we printed a disc using Verbatim's LightScribe v1.2 color CD-R media. For testing purposes, the quality has been set to "best". The results are shown below.
Verbatim CD-R v1.2 - 24 minutes |
More Features:
By looking at the picture below, you can see that LG's new Super Multi Blue drive is identified as an "HL-DT-ST BDDVDRW GGC-H20L."
The Nero screenshot also shows that the GGC-H20L has a maximum CD writing speed of 40x and a 2048KB buffer. This buffer is also backed up by some form of buffer underrun protection. According to Nero, the GGC-H20L can write CD-Text and overburn. When testing the drive's capacity I found that the drive was able to overburn up to 95:10with CompUSA's 99 minute CD-R media.
Using Alex Noe's Weak Sector Utility we were able to determine that the GGC-H20L is a "two sheep" burner. This means that LG's new drive is capable of backing up titles protected by SafeDisc 2, including version 2.51.
Here is a screen shot from Nero's InfoTool. This program queries the drive to see what its reading and writing capabilities are. InfoTool had no problems detecting the GGC-H20L's maximum reading and writing speeds, recording modes, buffer underrun protection and 2MB buffer.
InfoTool also shows that the GGC-H20L is an RPC-2 DVD drive. This means that the drive's region is stored in the firmware. The drive's region can be changed five times and after that it cannot be changed anymore. Unfortunately, a patched RPC-1 firmware is not yet available for this drive.
While InfoTool gives us a quick glance at the GGC-H20L's features, DVDINFOpro provides a little more information on some of the drive's reading and writing capabilities. By looking at the screenshot above you can see that LG's new drive can write to most DVD formats and has the ability to read both Blu-ray and HD DVD-ROM discs.
LG's new drive also supports a feature called "bitsetting." Using programs like Nero or CD Speed, you can set the book type of both DVD+R and DVD+R DL media to "DVD-ROM". For whatever reason though, the drive does not let you set the book type of DVD+RW discs.
For the GGC-H20L's software bundle, LG has once again turned to CyberLink. The CD that comes with the drive contains the CyberLink BD Solution suite which includes PowerProducer, Power2Go, PowerBackup, InstantBurn and PowerDVD.
CyberLink PowerProducer 4 - With CyberLink's PowerProducer you can create your own movie discs quickly and easily. Right from the start, this wizard based software gives you a number of options to select from. From here you can choose to produce a new movie disc, edit an existing one or record video directly to DVD.
PowerProducer lets you create a number of different movie discs. Looking at the menu below, you can choose to create a CD or DVD. The software also supports various disc capacities and formats including DVD-VR and DVD+VR.
While you can capture your own video, PowerProducer gives you the ability to import video files in a number of different formats. Once added to your production, you can use the built-in editor to trim, merge or split your video clips. PowerProducer also allows you to set chapters within the video content and add your own custom menus, backgrounds, fonts and titles.
CyberLink Power2Go 5.5 - Power2Go is the main disc burning program included with the GGC-H20L. With this software, users can create various types of CD's and DVD's or make backups of existing discs. Power2Go also offers enhanced security features, allowing you to password protect and encrypt your data discs.
CyberLink PowerBackup 2 - If you're looking for a quick and easy way to backup your data, PowerBackup is the answer. Depending on your needs, PowerBackup can do full, differential, and incremental backups as well as fast stream-to-disc archiving.
Backup jobs can be scheduled to run at regular intervals so the data is always protected. PowerBackup also offers more advanced features like file filtering, compression and password protection.
CyberLink InstantBurn 5 - InstantBurn is CyberLink's packet writing software. Like Roxio's Drag-to-Disc or Nero's InCD, it allows you to use your CD or DVD writer as if it was another hard drive or a huge floppy disk. Once formatted, you can cut, copy, and paste or rename files and folders oN a CD-RW or DVD±RW disc.
CyberLink LabelPrint 2 - The GGC-H20L also comes with CyberLink's disc labeling software. With LabelPrint, you can design and print labels, covers and inlays in four easy steps. Just select your template type, disc information, text layout, background image and print destination. LabelPrint also supports Labelflash and LightScribe technology, allowing you to burn images and text onto the surface of your discs.
CyberLink PowerDVD 7 - CyberLink's PowerDVD is one of the more popular software DVD players on the market right now. Along with support for DVD's, it can be used to play back Blu-ray Discs, HD DVD's and other high-def formats including H.264, HD MPEG-2, and WMV-HD. With its support for BD-J and iHD, PowerDVD also gives you the ability to access interactive movie content.
Unfortunately, the version of PowerDVD bundled with the GGC-H20L only supports 2 speaker output. If you want to take advantage of movies encoded with Dolby Digital or DTS, you'll need to buy the retail version of PowerDVD Ultra.
Like LG's previous "Super Multi Blue" drives, the GGC-H20L delivers a good number of features. The drive can read Blu-ray Discs at speeds as high as 6x and can play back the rival high-def format, HD DVD. On top of that, the GGC-H20L is backwards compatible with all major CD and DVD formats, including DVD-RAM. LG's new drive also includes features like a 4MB buffer, support for LightScribe and a great software bundle from CyberLink. With all this, it's easy to see why the LG GGC-H20L gets a solid 9 out of 10 for its features.
Along with smaller cable size, one of the biggest benefits of Serial ATA is its ease of installation. Because it uses a point to point connection, setting jumpers has become a thing of the past. In most cases, installation is as simple as plugging in the SATA and power cables and turning the computer on. Needless to say, it took only a couple of minutes to install LG's Super Multi Blue drive in our test computer. After making sure that the GGC-H20L was recognized by Windows, I was ready to start installing the software.
Software Installation:
As I mentioned earlier, the GGC-H20L comes with a CD full of software from CyberLink. If you have autorun enabled, the menu pictured below will automatically come up when you insert the disc.
You can view information on the different applications in the software bundle by clicking on the menu buttons. Otherwise, you can start the setup process by clicking the "Install Now" button. After picking your language of choice, you'll be presented with a number of installation options.
From here, you can choose to install PowerDVD, Power2Go, PowerProducer, PowerBackup, InstantBurn, LabelPrint or LG's firmware update utility. Simply select the components you want and click next a few times. Once the files are copied over, you can start burning your own discs.
The Documentation:
While the drive we received from LG did not come with any documentation, the company was able to provide a copy of the "User's Manual" in electronic format. Similar to the ones included with LG's other drives, this manual covers a number of topics. It starts out by going over the system requirements and the functions of the various buttons and connectors located on the front and back of the GGC-H20L. While the diagrams are small, they are clearly labeled and easy to understand. You will also want to pay special attention to the system requirements, especially if you plan to play Blu-ray and HD DVD movies protected by AACS.
From here, the manual jumps into the physical installation of the drive. The instructions cover all the basics including how to install the GGC-H20L into an empty drive bay and hook up the cables. The manual continues on by going over the basic operation of the drive. It explains how to insert and eject a disc and how to get one out of the drive in case of an emergency. Last but not least, it finishes up with a short troubleshooting section and a page full of specifications for the GGC-H20L.
Like LG's previous Super Multi Blue drives, the GGC-H20L was very easy to install. Even though Blu-ray and HD DVD are relatively new technologies, there were no problems getting the drive or the software installed and working correctly. Even then, if you do need a little help for some reason, the documentation LG has provided is more than sufficient. With this in mind, the GGC-H20L scores a 9 out of 10 for the installation portion of this review.
While CPU, memory, OS and other variables don't often make a huge difference, there are some nonetheless. We have a computer that is used only for testing hardware. We do this so all tests can be compared reliably.

For Blu-ray Disc Combo drives, the performance tests are normally broken down into five sections: CD read, CD write, DVD read, DVD write and BD read. Each benchmark test has been run three times. The score given is an average of the three. DMA has been enabled in device manager for all IDE devices supporting it.
CD Read Tests: For the read performance section of the CD-ROM benchmarks, CD WinBench 99 and DiscSpeed are used to test transfer speeds, seek times and CPU usage. For DAE testing, DiscSpeed is used to give an overall speed rating.
CD Write Tests: To test the write speeds, Nero Burning Rom is used to write 650MB and 700MB to our test media. Times are recorded. To test rewrite scores, Nero is used again to time how long it takes to write 400MB of random files and directories. Then Sonic's DLA is used to test packet writing speeds. The same files are copied and pasted in Windows Explorer and timed.
DVD Read Tests: For the read performance section of the DVD benchmarks DiscSpeed is used to test transfer speeds, seek times, and CPU usage.
DVD Write Tests: To test the DVD write speeds, Nero Burning Rom is used to write a 4.38GB image to our test media. Times are recorded. Then Sonic's DLA is used to test packet writing speeds. For this, 4GB of random files and directories are copied and pasted in Windows Explorer and timed.
BD Read Tests: For the read performance section of the BD benchmarks, DiscSpeed is used to test transfer speeds, seek times, and CPU usage.

The CD Winbench test is as close as we can get to testing every day usage. It fires off eight different applications using scripts. This tries to mimic the activities of a person loading these programs onto their own computer.
LG's Super Multi Blue drive gave us some mixed performance in our CD Winbench tests. While its overall score wasn't as high as the Sony's, its access time and transfer rates were fairly good. The GGC-H20L started reading at 19.3x (2910 / 150) and reached a maximum speed of about 39.3x (5910 / 150) on the outside.
Nero DiscSpeed 4 - Pressed CD:
For this test I used a pressed CD containing one Mode 1 data track. The disc is 74:38 in size and is full of data and directories.

Like the other drives, the GGC-H20L was a little faster when reading CD-R media. Thanks to this small speed boost, the drive was able to reach a maximum transfer speed of 40.91x.
While LG's new Super Multi Blue drive had no problems recognizing our 99 minute CompUSA media, it slowed down considerably when reading it back. As you can see, the drive reached a maximum transfer speed of only 10.56x.
Nero DiscSpeed 4 - CD-RW Media:
For this test I made a copy of a pressed test CD. I used some PNY 80 minute CD-RW media for the tests.

The GGC-H20L also reads CD-RW media at 40x. As you can see, the drive had no problems reaching this speed in our tests.
Nero DiscSpeed 4 (DAE) - Pressed CD:
For this test I used Pure Funk. The CD is almost exactly 74 minutes. This helps to squeeze the maximum performance out of the CD.
Exact Audio Copy can tell us a lot about a drive's capabilities. You can see from the screen shot that while the LG GGC-H20L supports accurate stream and has the ability to retrieve C2 error information from the CD, it does not cache audio data.

The GGC-H20L performed very well when ripping pressed audio CD's. With a maximum DAE speed of 40.36x, it had no problems taking the top spot in our tests.
Nero DiscSpeed 4 (DAE) - CD-R Media:
For this test I used a copy of the Pure Funk CD. It's burned onto the same Memorex Gold 74 minute media used in the data CD tests.

LG's new Super Multi Blue drive was a little slower when ripping audio CD-R discs. While the drive came very close, it wasn't able to reach 40x this time around. So how did it do in CD Speed's advanced DAE tests? Take a look below.
The GGC-H20L completed CD Speed's advanced DAE tests with an average score of 28.93x. The drive had no problems passing all of the on-the-fly tests and did not create any errors. If you look at the advanced features, you can see that the GGC-H20L was able to read the CD-Text, subchannel data and lead in but failed to read the lead out section of the CD.
CD Write and ReWrite Tests - Nero Burning Rom 7.10.1.0 andDLA 5.20:
For this test I randomly generated 650MB and 700MB of files and directories to test the time it takes the drive to write and close a CD. All of the files are between 1MB and 25MB in size and no more than 10 directories deep.
The GGC-H20L has a maximum CD writing speed of 40x. To reach this speed, it uses P-CAV, or Partial CAV, technology. By looking at the screenshot, you can see that the drive starts writing at 20x and accelerates, reaching 40x at about the 55 minute mark. This gave LG's Super Multi Blue drive an average writing speed of about 33.33x.
To test the drive's writing times, I wrote our test data to some Taiyo Yuden manufactured Fujimedia rated at 48x. The results are below.

LG's new drive did very well in our CD writing tests. Thanks to its 40x CD writing speed, the GGC-H20L was able to write an entire 701MB CD in 2:53, beating the drives from ASUS and Sony by nearly two minutes.
To test the drive's writing quality I used Lite-On IT's KProbe2. Written by Karr Wang, this utility can be used to test the number of C1 and C2 errors on a disc. For these tests I used a Lite-On LTR-52246S (firmware 6S0F) and read the discs at 32x.
The GGC-H20L's writing quality was very good. By looking at the KProbe screenshots, you can see that the discs burned by the drive had a low number of C1 errors. More importantly, there were no C2 errors at all.
For the rewriting tests I created 400MB of files on the hard drive and wrote them in DAO mode using Nero. To test the packet writing speeds I copied and pasted the same files off the hard drive onto a CD-RW disc using DLA from Sonic. Verbatim's 24x Ultra Speed CD-RW media was used for these tests.
While the GGC-H20L uses P-CAV when writing to CD-R discs, it uses Z-CLV, or Zone CLV, when rewriting at 24x. The drive starts rewriting at about 16x and then jumps to its maximum speed at the 9 minute mark.

The GGC-H20L wasn't as fast when reading single layer DVD-Videos. In our tests, it reached a maximum speed of only 8x when reading both single and dual layer discs.
To see how well LG's new drive worked as a DVD player, I watched a few scenes from Transformers: The Movie and Star Wars: The Phantom Menace using the bundled version of PowerDVD. The GGC-H20L had no problems playing back either movie and was fairly quiet.
DVD Write and ReWrite Tests - Nero Burning Rom 7.10.1.0 andDLA 5.20:
To test the DVD writing performance of LG's new drive I used Verbatim 16x DVD+R, 16x DVD-R, 6x DVD-RW and 8x DVD+RW media. To get the writing times, a 4.38GB image was burned to our test discs using Nero.
The GGC-H20L uses P-CAV, or Partial CAV, when writing to DVD+R and DVD-R media at 16x. By looking at the screenshots above, you can see that LG's new drive starts writing at about 6.9x and accelerates, reaching its maximum speed at about the 4.1GB minute mark.
LG's new drive also features 8x DVD+RW and 6x DVD-RW writing speeds. While the GGC-H20L uses CLV when writing to DVD-RW media, it uses Z-CLV to reach its maximum DVD+RW writing speed.

The GGC-H20L performed very well in our DVD writing tests. While not as fast as some of the 18x and 20x DVD writers we've looked at recently, it turned in some impressive times with DVD±R and DVD±RW media.
To check the media compatibility of the GGC-H20L, I ran a few tests using some of the media available in my area. The media types, along with the average time it took the drive to write our 4.38GB image, are listed below.

So what about writing quality? Testing a drive's DVD writing quality isn't easy. Until now, there were very few options, unless you wanted to shell out thousands of dollars for a certified test machine. Thanks to KProbe, we can test a disc's PI (Parity Inner) and PIF (Parity Inner Fail) rates.For these tests I used a Lite-On SOHW-1673S and read the discs at 4x with the PI and PIF ECC sums set to 8 and 1 respectively. For comparison, I also tested the discs on a BenQ DW1640. When combined with Nero CD Speed, the DW1640 is able to report PI Errors, PI Failures, Parity Outer Failures and even jitter levels. For this test, the discs are read at 8x with both the PI and PIF ECC sums set to 8.
So what are "good" results supposed to look like? With KProbe, the PI errors should not exceed 280 and the number of PIF errors should stay below 4. When testing with CD Speed, the number of PI errors should stay below 280 as well. However, because it scans with an ECC sum of 8, a higher number of PIF errors is acceptable, as long as they do not exceed 32. Since POF errors are uncorrectable, we really don't want to see any of them at all.
I also put these discs through a "stress test" by reading them back at 16x with the DW1640. By reading these discs back at this speed, we can see if there are any readability issues caused by the number of errors or high levels of jitter.

The GGC-H20L's writing quality was pretty good with most of the DVD+R media we tested. Aside from a few small spikes, the PI/PIF rates stayed within acceptable limits.

The GGC-H20L's packet writing performance was pretty mixed. While it turned in some very good writing times, it was not as fast as some of the other drives when reading back our test data from DVD+RW and DVD-RW media.
Double Layer DVD Write Tests - Nero Burning Rom 7.10.1.0:
To test the double layer DVD writing performance of the GGC-H20L, I used DVD+R DL and DVD-R DL media from Verbatim, RiDATA and Memorex. I created about 8GB of random files and directories on my hard drive and then burned them to our test discs with Nero.
LG's new drive had no problems writing to the Verbatim 8x DVD+R DL, Memorex 8x DVD+R DL, Verbatim 4x DVD-R DL and RiDATA 4x DVD-R DL media at 4x. However, with the 2.4x DVD+R DL media from Verbatim and Memorex, the writing speed was limited to only 2.4x.

The writing quality was pretty good with Verbatim's DVD-R and DVD+R DL media and Memorex's 8x DVD+R DL discs. Aside from a few small spikes, the PI/PIF rates stayed within acceptable limits and there were no readability problems. Unfortunately, the results weren't nearly as good with Memorex's 2.4x DVD+R DL and RiDATA's 4x DVD-R DL media. The error rates were considerably higher, especially when scanned with the DW1640.
Nero DiscSpeed 4 - BD-ROM:
To test the GGC-H20L's BD-ROM reading performance, I used the Blu-ray Disc version of The Fifth Element. This single layer disc is about 23GB in size.

While the GGC-H20L is rated at 6x when reading single layer BD-ROM discs, its speeds are limited to only 4.8x when reading AACS protected titles. In our tests, the drive started reading at 2.01x and reached a maximum transfer speed of 4.82x.
LG's Super Multi Blue drive had no problems playing back The Fifth Element using the bundled version of PowerDVD. Just keep in mind that if your monitor is connected to your video card using DVI or HDMI, both need to be HDCP compliant to play AACS protected titles. If not, you can still play them by switching the connection to VGA or using software like Slysoft's AnyDVD HD.
Nero DiscSpeed 4 - BD-R and BD-RE:
Next we'll look at the drive's BD-R and BD-RE reading performance. For this I created a few data discs using BD-R and BD-RE media from Memorex and Sony and then ran our BD read tests with CD Speed.

LG's new drive had no problems reading BD-R, BD-RE and BD-R DL media. In our tests, the GGC-H20L was able to read BD-R discs at 6x and BD-R DL media at 4.8x. Unfortunately, like the GGW-H20L, it reached a maximum transfer rate of only 2.3x when reading BD-RE discs.
Nero DiscSpeed 4 - HD DVD-ROM:
To test the GGC-H20L's HD DVD-ROM reading performance, I used the HD DVD version of King Kong. This double layer disc is about 27GB in size.

The GGC-H20L performed as expected when reading back our copy of King Kong. The drive started reading at 1.28x and reached a maximum transfer speed of about 3x at the midway point. Playing the movie with PowerDVD wasn't a problem either. However, as with Blu-ray Discs, there are certain hardware requirements if you plan to play AACS protected titles.
Performance Revisited:
Like LG's previous Super Multi Blue drives, the GGC-H20L performed pretty well in our tests. The drive had no problems playing back Blu-ray and HD DVD movies and was fairly quick when reading single layer BD-ROM's and BD-R media. Reading and writing to CD's and DVD's wasn't a problem for the GGC-H20L either. The drive had no problem reaching its rated read speeds and turned in some impressive times in our writing tests. With all things considered, the LG GGC-H20L gets a solid 8 out of 10 for the performance section of this review.
With their series of Super Multi Drives, LG has bridged the gap between Blu-ray Disc and HD DVD by giving users the ability to enjoy high-def movies in both formats. Unfortunately, the high price of these drives has put them out of reach for most consumers, especially those that are only looking to play movies. For these people, LG has introduced the GGC-H20L. While lacking the BD writing capabilities found on the GGW-H20L, the GGC-H20L delivers the same performance and features at a more affordable price.
When it came to playing high-def movies, the GGC-H20L handled both formats equally well. While I didn't get a chance to try any BD+ protected titles, the drive played all of the Blu-ray and HD DVD movies I had on hand using the bundled CyberLink software. The GGC-H20L also did fairly well in our transfer rate tests, reading BD-R discs at 6x and both Blu-ray Disc Movies and BD-R DL media at 4.8x. Unfortunately, its speeds were limited to only 2x when reading BD-RE discs.
LG's new drive also has the ability to read and write to all standard DVD formats, including DVD-RAM. The GGC-H20L performed very well when writing to DVD±R discs, taking less than 6 minutes to burn an entire 4.7GB DVD. The drive had no problems holding its own when writing to other types of media. However, the writing quality could have been better with some DVD±R DL discs. Nevertheless, the GGC-H20L was fairly quick when reading DVD's. In our tests, it was able to read single layer DVD-ROM's at 16x and DVD±R media at 12x but slowed to only 8x when reading DVD-Videos.
Reading and writing CD's wasn't a problem for the GGC-H20L either. In our tests, it read all types of CD media at 40x and had some fairly good seek times. This level of performance carried over to our DAE tests, where the drive ripped audio CD's at speeds as high as 40x. As a writer, the GGC-H20L performed as expected. The drive turned in some respectable times thanks to its 40x CD-R and 24x CD-RW writing speeds, and its writing quality was quite good as well.
LG's new Super Multi Blue drive also has its share of features. Along with support for both Blu-ray and HD DVD, the GGC-H20Lhas a 4MB buffer that is backed up by some sort of buffer underrun technology. While the drive only utilizes 2MB of the buffer when writing CD's and DVD's, this system worked flawlessly in our tests. The GGC-H20L also supports HP's LightScribe Direct Disc Labeling system and has the ability to set the book type of DVD+R and DVD+R DL media. Last but not least, LG has included a great software bundle from CyberLink.
LG's new Super Multi Blue drive is available now and can be purchased through some of the online vendors listed on Pricegrabber. Prices vary depending on the seller, but the GGC-H20L can be picked up for less than $250.
