The main issue I see with using BTRFS with MDADM is that you lose the benefit 
of bit-rot repair. MDADM can't correct bit rot, but BTRFS-Raid (and ZFS raid 
arrays) can, but only with native raid configurations.

AFAIK:

1.  mdadm RAID1 can fix bit rot, so long as one drive has a good block 
to fix the others.

2.  btrfs on top of mdadm RAID1 will not see the bit rot that mdadm 
RAID1 fixes.
