A git repository is a content-addressable object store where objects go in indexed by the SHA1 of their content, plus a set of named references pointing at specific objects by hash. The on-disk format (loose objects as individual files, packfiles as delta-compressed archives with a separate index, a ref store split between a directory of files and a packed-refs flat file with a locking protocol that breaks on NFS) is an implementation detail. The protocol for synchronising objects and refs between repositories is what actually matters, and since git-the-program is just one implementation of it, you can swap the storage backend without clients noticing.
