We're in the process of converting to Git at work, and I've found that svn-all-fast-export was the best option for us. git-svn's behavior of a branch's entire history every time it found a new branch (even though it has already seen 3/4 of the revisions involved) caused it to be far too slow for our needs. Admittedly, this was ~1 year ago that I tried git-svn to do a test conversion, and things might have improved since then.

svn-all-fast-export does require access to the raw repository, instead of just (http|svn|svn+ssh):// access, but it does allow you to split out one SVN "repository" into multiple Git repositories in one go.
