The more I use my Plextor 8/4/32, the more I think that Burn-Proof technology is intended more as a placebo effect than anything else. Whatever I do with my outdated BP6/Cel366@468, the drive keeps burning away at 8X speed without a hiccup. Maybe it's necessary if you're running on a Pentium/133 or something, but in that case I think you have more pressing concerns than a CD burner.
