Hardrive Size for 720P feauture vs. 1080P feature

I'm looking at external harddrives and I'm curious as to how much space I would need if I were to store say 10 hours of footage at 720P vs 1080P. I'd like to shoot at 1080P of course but it may be cost and size prohibitive.
 
DVCPRO HD 720p60 running at 59.94 = 524.79 GB for 10 hours.
DVCPRO HD 720p24 running at 23.98 = 214.06GB for 10 hours

DVCPRO HD 1080i60 at 23.98 = 421.22 GB for 10 hours
DVCPRO HD 1080i60 at 59.94 = 1.04 TB for 10 hours

Got this handy thing called the AJA Data Rate Calculator. Google it. It is on the AJA site.
 
Thanks for that converter link. I have been pouring over these forums for the last few days but I am still unsure about one thing regarding the HVX data rate.

If you use FCP on a powermacbookpro (let's just say a mac laptop) and record to the internal/external drive is the data rate less with the lesser frame rate?

I keep seeing little bits of info that lead me to believe that if I shoot 720 on the P2 card I can save space by going from 60p to 24. But that might not translate to the data spit out the firewire connection to the laptop? I mean that is what 24pa, 24pn, 24pz :) are about but the info is spread out all over the place that I feel I can't get to an informed answer on my on research.

My specific need is that I want to shoot a ballet that has 2 acts which are each 1 hour long. I would love to go straight to a laptop drive but would be fine with an external USB/firewire400/800 drive. If going to 24p saves a lot of space and bandwidth I would be happy to shoot with it, or 30p if temporal problems with the movement were too much.

EDIT- and now I see this thread was about P2 cards. HOpe this question doesn't mess things up.
