Partitions for Installation

Hi there

I'll install fedora 19 in a few days on my pc. I've go a 250GB SSD and a 1 TB HDD.
Parallel i install Windows 7 with a reservation of 700GB on the HDD.

So i've got a 250GB SSD vor Fedora and another space of 300 GB on the HDD for fedora.
Which sizes should i make the partitions for fedora? Is it fine if some space is on the SSD and some on the HDD or shouldn't i do this?

Or would i be anyway better if i installt Windows 7 virtual unter fedora?

Kind regards, Cellar Door
