Writing Data CD-R/RW discs:

The specifications state that the drive should be able to write CD-Rs at 40x and CD-RWs at 32x:

Taiyo Yuden "Full Face" Printable (52x)

The LG GSA-4165B uses Z-CLV, (Zone-Constant Linear Velocity) to write CD-R's at 48x. This gives an average writing speed of 33.72x and a writing time of 3 minutes and 8 seconds. Even though the official specifications states a 40x writing speed on CD-Rs, our test drive wrote CD-Rs at 48x.

The LG GSA-4165B uses Z-CLV, (Zone-Constant Linear Velocity) to write CD-RWs at 32x. The average speed is 29.25x and total writing time is 3 minutes and 14 seconds.

In this first look, we did not include any quality scans of the CD-R/RW discs.

DVD-Writing performance:

The specifications of this drive tell us that it should write DVD±R DL at 4x, DVD±R at 16x and DVD+RW/-RW at 8x/6x.

DVD+R at 16x:

The LS GSA-4165B uses P-CAV (Partial-Constant Angular Velocity) to write DVD+R at 16x. This gives an average writing speed of 12.68x and a writing time of 5 minutes and 31 seconds.

Above a KProbe quality scan of the Ricoh DVD+R 16x disc, and the result is very good.

Verbatim 16x DVD+R media, average writing speed of 12.66x, and a writing time of 5 minutes and 32 seconds.

Excellent KProbe result.

DVD+RW at 8x:

The LG GSA-4165B uses Z-CLV (Zone-Constant Linear Velocity) to write DVD+RW at 8x. The average speed is 7.80x and total writing time is 8 minutes.

The Kprobe result is very good.

DVD-R at 16x:

The LG GSA-4165B uses P-CAV (Partial-Constant Angular Velocity) to write DVD-R at 16x. This gives an average writing speed of 12.67x, and a writing time of 5 minutes and 21 seconds.

And the same goes for the Verbatim media. Could there be a bug in the firmware DL04 ?
