Asus 24b1st

Does anyone know if this drive is riplocked? I just installed it and it took 17 minutes to rip a 7.1GB disc. It came with firmware 1.05. Does that rip time sound normal? I was thinking I’d be closer to 10 minutes. It also took 12 minutes to burn that data to a DVD-R (4.7GB) which didn’t seem blazing fast either. Just looking to make this drive perform to it’s highest potential. Any help would be appreciated.
