Manufactured: April 2004

It has been a while since last time we looked into a BenQ drive, so it will be interesting to see where they are now and how their products are. The drive they sent us is their latest DVD-Writer; the BenQ DW830A. The drive we got here is a pre-release drive with unfinished firmware so we find it a bit useless to do a full review before the final firmware arrives. What we will take a look at is the features and the dual layer writing capabilities as they are now. Just to give you a taste on what to expect from the first generation dual layer capable drives. We will try to look at compatibility, quality and speed.

The most important feature of this drive is of course the Dual Layer capabilities. Beside this it doesn’t seem to be very special, but let’s forget that for now and concentrate on the dual layer writing capabilities. We will of course come back with a full review including updated dual layer tests when the firmware and media is finalized.
