Anyone know the internal Hard Drive speed?
First of all your PB 12" has a 4200RPM drive.
In your PB a 4200 drive is NOT going to make a lot of difference in speed vs a 7200. There aren't the same bottle necks as there are in PCs.
Booting off a FW HD is going to be most likely the same speed as ur internal because it's not on the IDE Bus. Your internal ATA/100 HD gets speeds of up to 298Mbps.
Use the Firewire for storage. I wouldnt recommnend booting up for it all the time. Especially because then you have 2 different systems one when you are at your desk and one when you are travelling or not at your desk.
Apple uses the slower drives to keep heat and battery consumption down.
All PB's have 4200 drives. And you really shouldn't even notice. If you want to do anything to ur PB to speed it up...MAX the RAM.
