Full git repositories are normally smaller than svn working copies -
and that's the
case here. By using git you'll be saving a bit under 200M. If you're
curious why,
it boils down to git storing the repo very efficiently and svn needing
two copies
of every file in a working copy.

In addition if you're really concerned about disk space you can always
go into the git
repo, change to the branch you want and then delete the .git
directory. But if you
were keeping the .svn directory I don't see the point since...

373M fpc.svn/.svn
185M fpc.git/.git

People think that and in my experience they are usually wrong. You
have opinions.
And that's fine. Enjoy them. As noted above, a checked out git repo is smaller.
Subsequent fetches will be far faster. In this case, as the data above
shows, your
workflow will improve.
