Stepping up from the BenQ DW1620 Pro, BenQ is still trailblazing with the DW1640. This 8x DVD+R DL is setting the benchmark in double-layer burning, as is BenQ's $89 price tag. Across the board for all media this is a fast drive, only falling down a little with the DVD-RW turning in a 6x rate and no support for DVD-RAM.

The package is rich in features, with plenty of innovations to ensure quality burning. Write Right technology, Walking Optimal Power Control II, Anti-Dust Cooling System and the Air Flow Cooling allow for precision and temperature stability, but how good is the output? Good enough.

The 8.5GB DVD+R DL test burnt with a transfer rate of 8.9KBps which translates to a full disc in just 15 min. Equally impressive was the 4.2GB DVD+R 16x burn at 12.5KBps and transfer speed to the hard drive of 10.9KBps.

BenQ's bundled software includes Nero and its own Qsuite, that allows a lot more configurability and control of the drive. The best function here is the ability to change the Book Type settings so that any DVD+ media you write to will appear as a DVD-ROM, so it will be readable in older drives and DVD players. This setting is not the default, so be sure to change it before laser hits plastic - it is a huge plus in this drive's favour.

The QSuite also allows for a significant amount of media diagnostics before burning, so you can check for a warped disc or a range of other errors.
