DVD+R/-R Double Layer writing speed and compatibility:

The LG GSA-4166B supports DVD+R Double Layer at 8x and DVD-R Dual Layer at 4x for writing discs with a size of around 8.5 GB.

First up is Maxell DVD+R Double Layer 2.4x

This Maxell media is manufactured by Mitsubishi Kagaku Media and is supported at 6x write speed. Thanks to Maxell America for sending us this media.

This is a very good result. The transfer curve shows no problems reading this disc.

This media is made by RiTEK Corporation and is supported at 4x write speed. Thanks to Memorex for sending us this media.

This is not such a good result producing a very large PIF count on the first layer. The transfer curve shows the read back problems.

This Verbatim media is made by Mitsubishi Kagaku Media and is supported at 8x write speed. Thanks to Verbatim USA for sending us this media.

Many drives show this quirk of reaching 8x on the first layer and then falling back to 4x when writing the second layer. However the result is very good and the transfer curve shows no problems reading this one back.

Let's compare the LG GSA-4166B results with some other DL capable drives.

*1 Verbatim DVD+R DL
*2 Traxdata DVD+R DL
*3 Ricoh DVD+R DL
*4 DataWrite DVD+R DL
*5 Memorex DVD+R DL
*6 Maxell DVD+R DL

DVD-R DL

As mentioned earlier, the LG GSA-4166B supports the DVD-R DL standard at 4x.

Let's find the manufacturer and media information too, for this we will use CD-DVD Speed:

This Verbatim media is manufactured by Mitsubishi Kagaku Media and is supported at 4x write speed. Thanks to Verbatim USA for sending us this media.

Another great result with Verbatim media. The transfer curve shows no problems on read back.

Summary: The LG GSA-4166B produces good quality burns on the Mitsubishi based DVD±R DL media.

Before we round off this review, let us run the drive through some advanced tests at next page…
