Don't forget that FreeBSD 7 includes ZFS support, so
there's another option for you there.

I reckon if you're going to compare apples to apples
then you probably want to test it against a Linux
checksumming filesystem, the only real contender
I'm aware of being btrfs (still pre-alpha).
Alternatively you can disable checksumming on a ZFS
volume and retest it against XFS, etc.
zfs set checksum=off foo/bar
