We are currently using Subversion as our source code repository. We are in the planning phase of converting to Git. Our Subversion repository is currently 19Gb. How does a Git repository compare to Subversion on disk space requirements? What will my 19Gb svn repository translate to in a Git repository.

It’s hard to guess the exact size that your Git repository will take because it depends on several factors, for instance
Git has a good compression algorithm and, from my past experience, it was able to reduce the size of a SVN repository up to 10 times. Here’s some examples.
However, the best way is to try it yourself. On your local machine you can convert the SVN repository into Git
then run
git gcand see how much space you need to start.
