iCloud storage is not directly accessibile in the manner of the MobileMe iDisk: it's for email, 'Photo Journal' (populated from iPhoto for iOS), backup of iOS devices (not Macs) and 'Documents in the Cloud', which are iWork documents uploaded from within the applications. All these facilities other than Mail require Lion 10.7.2 at minimum and the iCloud Preference Pane does not appear on earlier systems. You can't get a readout of the amount of storage used on Snow Leopard for this reason.

Thank you. Very clear answer. 5 GBs should be plenty for my Mail storage. I assume that my storage should be about the same as the size of the MAIL folder in the Library file folder? I have less than one GB in MAIL according to Quick Look.
