HD- how big a file on your hard drive?

As I continue to study camcorders- the question arose- if you're recording
to a hard drive- how much data is being created per second for say 1080i?
Since I'll buy a second drive just to store the filming- I need to know.

For example, I see one Sony camcorder with a 30 gig hard drive. If all
recording was at 1080i, you'd end up with how much filming in minutes?

I've also realized that if the answer is several hours- I'll need a number
of extra batteries, right?
