Mac Mini running OS X Lion:

Filesystem      Size   Used  Avail Capacity  Mounted on
/dev/disk1s2   391Gi   55Gi  336Gi    15%    /
/dev/disk0s2   465Gi   66Gi  399Gi    15%    /Volumes/Work
/dev/disk1s4    37Gi  149Mi   36Gi     1%    /Volumes/Data
/dev/disk1s5    37Gi  149Mi   37Gi     1%    /Volumes/User Data
