detail information

The specifications state that the drive should be able to write CD-Rs at 48x and CD-RWs at 32x.

The BenQ DW1670 uses CAV (Constant Angular Velocity) to write CD-R's at 48x. This gives an average writing speed of 36.45x and a writing time of 2 minutes and 43 seconds.

The BenQ DW1670 uses CAV, (Constant Angular Velocity) to write CD-RWs at 32x. The average speed is 23.97x and total writing time is 3 minutes and 56 seconds. This is very interesting because most other writers use a Z-CLV technique for CD-RW writing.

In this preview, 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/-R DL at 8x/6x, DVD±R at 16x, DVD+RW/-RW at 8x/6x and DVD-RAM at 5x.

DVD+R at 16x:

MCC004

The BenQ DW1670 uses CAV (Constant Angular Velocity) to write DVD+R at 16x. This gives an average writing speed of 11.95x and a writing time of 6 minutes and 03 seconds.

The Kprobe scan above shows a very good result.

CMCMAGM01

16x Memorex DVD+R was easily written at 16x.

Writing quality on this Memorex CMCMAGM01 16x DVD+R media does not look so great. This might be due to poor media quality or a poor writing strategy. BenQ might need to work on this...

DVD+RW at 8x:

RITEK008

The BenQ DW1670 uses Z-CLV (Zone-Constant Linear Velocity) to write DVD+RW at 8x. The average speed is 7.72x and total writing time is 8:25 minutes.

The first burning zone (6x) doesn't look so hot, but the rest of the graph looks great. The media used here is Memorex 8x DVD+RW.

DVD-R at 16x:

MCC03RG20

The BenQ DW1670 uses CAV (Constant Angular Velocity) to write DVD-R at 16x. This gives an average writing speed of 11.87x and a writing time of 6 minutes and 19 seconds.

16x DVD-R media from Verbatim looks okay.

CMCMAGAM3

Memorex 16x DVD-R media was burned at 16x.

Writing quality might need some improvement with this Memorex 16x DVD-R media.

DVD-RW at 6x:

MKM01RW6X01

The BenQ DW1670 uses CLV (Constant Linear Velocity) to write DVD-RW at 6x. The average speed is 5.96x and total writing time is 10 minutes and 37 seconds.

6x DVD-RW writing quality on this media looks very good!

DVD+R DL at 8x:

MKM003

The BenQ DW1670 uses Z-CLV (Zone-Constant Linear Velocity) to write DVD+R DL at 8x. The average speed is 6.33x and total writing time is 20:51 minutes.

The writing quality with Double Layer media looks excellent!

DVD+R DL at 6x:

MKM001

The BenQ DW1670 uses CLV (Constant Linear Velocity) to write DVD+R DL at 6x. The average speed is 5.71x and total writing time is 21 minutes and 24 seconds.

Another nice Double Layer result from the BenQ 1670.

DVD-R DL at 6x:

MKM01RD30

The BenQ DW1670 uses CLV, (Constant Linear Velocity) to write DVD-R DL at 6x. This gives an average writing speed of 5.68x, and a writing time of 21 minutes and 33 seconds. A glitch in Nero CD-DVD Speed caused the black bar to appear on the left side of the image.

This graph shows a few spikes that might be an indication of some trouble with this disc.

DVD-RAM at 5x:

Maxell 5x DVD-RAM

The BenQ DW1670 is able to write to Maxell 5x DVD-RAM media without any problems. The DVD-RAM verify feature is turned off to achieve a full 5x writing speed.
