Because of the size and convenience (not planning on using an A/C Adapter), I am considering the purchase of an external portable hard drive.

I would prefer one having Firewire verses USB 2.0, but I have seen any.

I have heard that using a portable hard drive without an A/C adapter will be very draining on the MacBook battery. Has anyone experience this problem?

I have also heard that voltage can be an issue with portable hard drives. Has anyone heard or experienced this problem?

Any brand recommendations for those that are using a portable hard drive?

Thank You
