Here's a review of the DW830A at the hardwarezone.com. Something interesting are questions asked of BenQ and the answers. Here's a few:
about speed increases:
The DL ver. 2 standard for 4x-10x recording is expected to be finalized by Q4 2004. The BenQ DVDRW product roadmap has been planned accordingly to launch 4x DVD+R DL recording supported drive in Q4/04, and 6x-10x DVD+R DL recordable drives in 2005.
about media price:
Initially when the DVD+R DL media first becomes available to end users in June, the estimated retail price is within US$15. Should such price drop to US$5 by Christmas; it would greatly increase DL recording demand.
