Git is not a storage system at all. I was talking about actual physical storage systems that drive requirements for storage software, and there don't seem to be many petabyte-level git repositories. Git doesn't even qualify as storage software, as it delegates all of the real storage tasks to filesystems and such. It's an application that uses storage, much like every other application from emacs to Excel.
Also, have you noticed that git is in user space? Must be a toy, then. Just ask Linus.
