Yes you can. With 3 drives, however, performance will be awful (at
least with layout far, 2 copies).

IMO raid10,f2 is a great balance of speed and redundancy.
it''s faster than raid5 for reading, about the same for writing. it's
even potentially faster than raid0 for reading, actually.
With 3 disks one should be able to get 3.0 times the speed of one
disk, or slightly more, and each stripe involves only *one* disk
instead of 2 as it does with raid5.
