So that is 35GB per tree. If you just did that same amount for 9 version 4's, 7 version 5's and 3 version 6's ... that would be 19 ... so lets call it 20 ... trees. 20 x 35 GB is 700GB or ~7x the amount we currently have It would also take 7x more bandwidth and 7x more time to move the trees around. -------------- next part -------------- A non-text attachment was scrubbed...
