Massive file duplication with several working copies / which linux filesystem to use

Hi all,

We have 5 developers, each of them has a workspace on our linux
workgroup server. The workspaces constist of working copies checked out
from our SVN repository. The workspaces have grown rather big in our
case, we have like 20 GB per developer.

That's a 100 GB worth of working copies of pretty much the same things.
  If all developers had clean working copies of exactly the same
revisions of exactly the same SVN checkouts, this would mean we store
each file ten times. (!)

Now that's a massive multiplication of bytes. I'm not blaming SVN, it's
doing what we want it to do. I'm rather looking one level below, at the
filesystem that stores all these workspaces. If the filesystem could do
online deduplication, it would mean a huge saving on disk capacity for us.

We would also like to move the workspaces to a solid-state drive, for
faster builds.

Which linux filesystem would you recommend?
