A complete git repo is usually smaller than a complete SVN one
(according to "common knowlege" - as in, I didn't run any benchmarks),
but one commonly only checks out the /trunk subdirectory in subversion,
while git usually checks out the whole project history, including all
branches - it could be a substantial amount of data you don't check out
with SVN.

Well,

Actually the quotes from the GitSvnComparsion page are very misleading, it is true that a git working directory needs less space than an svn working directory, it is also true that a git repository is smaller than an svn repository. The main difference is that with git, you *clone* a repository, and then create a working directory out of it, so you need sizeof(repo) + sizeof(git-working-directory) on your hard disk, while with svn, all what you need is sizeof(svn-working-directory).
