I also seem to remember that one suggestion was to use larger block size. I have a pair of 2 TB hard drives assembled in a gmirror, which is to be added to an existing server. There will be 3 partitions about the same sizes on the 2 TB mirror. What block size should I use if I'd like to use freebsd-snapshots? -- Janos Dohanics
