What I'd do, is backup your documents to an external drive, then see how much space you used for the OS and applications you use regularly. Add enough space for updates and new sottware you're thinking of adding. Then add another 10 - 20GB for grins. The rest can be your data partition. I'm of course assuming an adequate size HDD. If not, buy another one and use one for data and the other for the OS and applications. You can never have "too much" free space on a drive.
