I currently have the 8/4/32 model and I'm going to do a system rebuild coming up and I thought it would be nice to possibly upgrade to the 16x model. What I'm wondering though is how good they are. I've heard that Plextor disabled some stuff in the firmware on the newer models awhile back so I don't know if it was confirmed or not. I've been very happy with my 8x model, since it's been able to burn everything including Safe Disc 2 protection. However, if the 16x is capable of doing all of this without any firmware hacking I'd probably be interested in upgrading for the speed increase.
