The KProbe result is good, but the reading curve shows some slight problems. This could be due to various reasons; one reason is that we have seen that NEC drives have some slight compatibility problems with Ritek +/-R media for reading. Other reasons could be jitter or reflectivity issues. But in practical use there should not be any problems.

No problems with this media.

Overall thoughts: The writing quality is for the most part very good, and the media compatibility is good as well. But the OPC function seems to be over sensitive and several 16x discs did not write at 16x. And it's a bit disappointing that the drive only supports 8x DVD-R when all other new drives support 16x DVD-R.

Re-Writing data:

The BenQ DW1525 supports rewriting DVD-RW at 4x and DVD+RW at 4x speed; let us write two discs in Nero CD/DVD speed and Nero Burning ROM to see how fast it is.

Here are the writing results for writing the 4x DVD-RW disc:


 

BenQ DW1625 uses CLV writing technology to write the DVD-RW disc at 4x. Total recording time is around 15 minutes.

And here is the result with 4x DVD+RW writing:

BenQ DW1625 uses CLV writing technology to write the DVD+RW disc at 4x as well. Total recording time is around 15 minutes.

Writing Quality with DVD Re-Writable discs:

Due to request from our readers we will add a few write quality tests with ReWritable media. Settings and testing procedures are the same as used earlier in this review so you may want to go back and read them if unsure. All discs used for these tests have been written to before, but none have been written to more than 25 times.

The result with this media is quite disappointing; BenQ needs to improve writing quality with this media.

The result is acceptable, but there is another issue with the DVD-RW discs; Most drives can't detect the discs! Our default reading curve drives Plextor PX-712A and NEC ND-3540A could not see the DVD-RW discs written by the BenQ DW1625.

First - the result is not very good, but there is another issue with the DVD-RW discs; most drives can't detect the discs! Our default reading curve drives Plextor PX-712A and NEC ND-3540A could not see the DVD-RW discs written by the BenQ DW1625.

To sum it up: The DVD+/-RW writing quality is not good at all, and BenQ need to fix the compatibility issues with DVD-RW discs.

But let us now look at another aspect of this drive; double layer DVD+R writing…
