OK so just becuase we have serial hard drives we can go above the 137GB barrier. But those of us with 32 bit systems are limited to 2.2TB drives. Now this may be fine for some time. I'm not sure if the fact if Leopard is a 64 bit system but my Dual G4 is still a 32 bit CPU am I stuck at 2.2TB drives. This may not be a big deal right now since Seagates 750GB is the largest on the market and it will probably take two more years before hard drives come close to that size. Does anyone know what the max hard drive capacity is for a 64 bit system?
