I guess a corallary would be: will btrfs stripe over the mirrored pairs until the smaller pair fills up and then continue writing to the larger pair? Also, if raid10 is used with, say, 3 100gb drives and 1 250gb drive would the 250gb drive be able to fail without data loss? Could it be fully utilized? How about with a 500gb drive? Thanks, Brian
