DVD-RAM:

The LG GBW-H10N is a so-called Super Multi Blue, meaning it also supports writing and reading the DVD-RAM format. Let us look at the recording side of the disc, and as you can see it has differences from the other DVD+R/W/R9 DL and DVD-R/W discs.

On the data side, we can see a very fascinating pattern of lighter spots, supposedly these spots are used for calibration while writing and reading.

A DVD-RAM’s disc can be formatted in the following formats: FAT32, UDF 1.02, UDF 1.50, UDF 2.00, UDF 2.01, and UDF 2.50.

By formatting a DVD-RAM disc with FAT32 it will act like a removable hard drive and all writing will be done as “background processes”. Meaning you do not have to wait for it to finish, you can start or work with other applications while the DVD-RAM is working without noticing any “hangs” or CPU slowdowns.

Lets us take a look how the drive performs:

Maxell branded 5x media manufactured by Maxell.

Writing Maxell 5x with Streaming enabled

Writing Maxell 5x with Streaming disabled

Transfer Rate test

ScanDisc

As we can see, the LG GBW-H10N reads and writes Maxell 5x DVD-RAM without any problem.

Verbatim branded 3x media manufactured by MEI.

Writing Verbatim 3x with Streaming enabled

Writing Verbatim 3x with Streaming disabled

ScanDisc

As we can see, the LG GBW-H10N reads and writes Verbatim 3x DVD-RAM without any problem.

For those of you who are not familiar with DVD-RAM, you may probably think that something went wrong during the write process with the verification turned on, since the 3x and 5x media was written at 1.3x and 2x, respectively. But don’t worry, that is pretty normal for DVD-RAM discs. The reason for the lower writing speed is, the drive constantly reads back the data after writing it to verify that it’s written correctly. We can also call it a “bullet proof” writing/verify technique, with no data loss/errors.
