LG GSA-H22N Super Multi DVD Burner Review

Before we complete this review, we will run some advanced tests on the LG GSA-H22N.

 

The "Sheep Test":

LG GSA-H22N Super Multi DVD Burner ReviewFor this test, we will use the sheep tests made by Alexander Noé. Why is it called sheep test? That’s because the logo of the first 1 to 1 copy program called CloneCD is a sheep. When looking at supported writers, you will notice that the feature list has sheep to indicate if a feature is supported or not.

In this case we are interested in the writer’s ability to backup/write weak sectors. Also called: "Correct EFM encoding of regular bit-patterns."

  • No sheep: Can’t backup any Safedisc 2 versions without the help of software tricks
  • 1 Sheep: Can backup Safedisc 2 up to version 2.4x without software tricks
  • 2 Sheep: Can backup Safedisc 2, including version 2.5x
  • 3 Sheep: Can write all possible weak sectors, few if any writers could do this.

One of our forum moderators, Womble, has written a guide concerning the "Sheep Test" that can be found here.

In the screenshot below taken from CloneCD, we see the LG GSA-H22N supports all features CloneCD tests for.

The LG GSA-H22N is a "Two Sheep Burner" that can successfully write Safedisc up to V2.51.

 

16x and 18x DVD writing in an external enclosure:

We have placed the LG GSA-H22N in an external FireWire enclosure built around the Prolific PL3507 chipset for the following test burns.

A 16x DVD+R burn completed in 5 minutes and 42 seconds, the same time as it would have taken in an internal setup.

The drive’s buffer level is stable all the way to the end of the burn, demonstrating the drive’s ability to communicate at 22 MB/s necessary to achieve the full 16x speed.

An 18x burn shows signs of exceeding the maximum data transfer rate possible in our setup, but the LG GSA-H22N manages to complete the 18x burn without a significant slowdown, in 5 minutes and 17 seconds. This is about 15 seconds longer than it would have taken in an internal setup, but still quite impressive for a drive in an external enclosure.

The quality of the burned disc is nothing short of excellent, even in the final area where the drive was forced to repeatedly suspend and resume burning. We can observe some additional PI failures near the end, but their number is minimal, a testament to the drive’s good implementation of buffer underrun protection.
