I thought I would give Plextor's "Burnproof" technology a run for the money.. so I did a CD to CD copy, while I played a game of Q3F (Quake 3 Fortress).. I thought at least I might be able to get burnproof to kick in, and slow down the burn.. but no.. Not only was burnproof not needed, but it burned at the full 12x speed.. 6 minutes or so... This is of course with an all SCSI system, not sure if an EIDE burner could do that or not.. Pretty damn cool though.
