I just bought a new 160 GB hard drive, and currenly have a 80 GB hard drive. Both are 7200 RPM. Which one should I use as master? How would you partition the 160 GB drive, and how much space would you allocate each partition? Would you partition the 80 GB as well too? I'm currently using 75-ish GB. I was thinking maybe splitting the each in half, so i'd have 80+80 and 40+40, how does that sound?
