You should look into how git is architected to support a lot of features SVN doesn't (distributed repos is a big one). When you clone a git repo you clone the full file history. This is trivial for text but can be extremely large for binary files.

Storage is not storage as you can store things as copies or diffs (and a million other ways). For code, diffs are efficient but for binaries, diffs approach double the size of the original files, simply sending/storing the full file is better.

These differences have big effects on how git operates and many design choices assumed diffable text assets only.

If you do a little research, there's plenty of information on the topic.
