18x dvd burners are hype, they're bairly a hair faster then 16x drives.
a buncha years ago I bought a Kenwood TrueX 72X cd-rom. It was BLAZING fast, of couse it died within 60 days, as did I believe 100% of the drives. The dual laser technology was interesting, and I think should have been researched and worked on further. While I don't know details about how burners work so Ic an't possible say "it'd be easy!" I'm sure they could come up with multi-laser burners. Then we could get faster burns, with lower disc speeds. I know my TrueX drive spun about what a 32x drive does. And it was seriously 2+ times faster then any CD-ROM drive I've ever used, even up until today. With 2 lasers on a burner we could see a dvd burn in like 3 minutes that would be awesome. Obviously this isn't as easy as I'm making it out to be or some company would have already released it. But, I think this has to be the future, as BlueRay burners will take forever to burn the disc's when they hit the 100gig mark.
