Depends on whether you plan on crashing or not :) According to
http://lists.freebsd.org/pipermail/freebsd-fs/2003-July/000181.html,
you may not want to create filesystems over 3TB if you want fsck to
succeed. I don't know if that's using the default newfs settings
(which would create an insane number of inodes), though.

To sustain only 30MByte/s across the entire set? Doesn't really
matter, since even a single disk could do that.
