That's not (really) true. For RAID10 you need 4 block devices (could
be all on one disk, but seriously...) -- RAID10 is STRIPED and
MIRRORED, so you need at least 2 devices to MIRROR and at least 2
MIRRORS to STRIPE. A 3 legged monstrosity could be some ugly
combination of a RAID1 + RAID0 or A RAID0 + RAID1, but would not
really be striped & mirrored.
