Ok, itunes fucked up my music again. I have backed up all my music but all my ratings and etc are gone. So I am done with the nvidia raid that I have previously used. So I have two options. I'll be reusing my 2 320gb hd Build a seperate system, run windows server or linux and run RAID1 found someone selling P4 630 Prescott 3.0GHz 2MB L2 Cache with Asus P5LD2 motherboard for $80bucks Add some ram and i'll be set. or Adaptec SATA RAID controller, model AAR-2410SA for $100 add it to my existing system I have no clue how controllers work, but everyone raves about hardware raid. So OT, whats my best choice?
