Quality test
Transfer rate test
Verbatim 2.4x DVD+R DL media made in Mitsubishi's Singapore facility has a well-deserved reputation for high quality.
BenQ may have been too conservative to limit this media to 4x, but the results at 4x are quite spectacular, as you can see.
Verbatim 8x DVD+R DL

Quality test
Transfer rate test
There is a rise in PIE levels typical of MKM 003 from the 15-pack we use, but it is nothing to worry about. The transfer rate test shows perfect readability and PIF levels are remarkably low, always a sign of good quality media.
Memorex 2.4x DVD+R DL

Quality test
Transfer rate test
A good burn of a widely used DVD+R DL media type that can be trouble with other drives. Not only that, BenQ DW1800 manages to overspeed this media to 4x as well. We are very impressed.

Quality test
Transfer rate test
A barely acceptable burn. Obvious quality problems throughout the second layer show in the transfer rate test as well.
Summary
From our limited testing, BenQ DW1800 appears to be a good DVD+R DL writer, capable of excellent burns with Verbatim media and quite good with the common 2.4x media from Ritek.
DVD-R DL writing quality
In the tests below, we will explore DVD-R DL writing speed and quality of BenQ DW1800 with media from two manufacturers.

An absolutely great burn of high-speed DVD-R DL media.

Quality test
Transfer rate test
This burn of DVD-R DL media proved to be unreadable about 20% into the second layer.
Summary
BenQ DW1800 failed to burn one out of two DVD-R DL discs we tried.
DVD-R and DVD-RW writing quality
This is due to a rarely noticed SHM-165P6S behavior.
It reads 8x DVD+R and DVD-R media at 12x CAV.
