I will never be worried for space. Besides, I used to only have 100 gigs dedicated to it with the rest being for laptop backups, but I won a 1TB hard drive a few months ago. I use the 1TB one for my laptop now and use the 500 gig one exclusively for my Wii, for the most part. I'd like to dedicate 16 gigs of it, though, to the 360.
