The hardware is an external 2TB bus powered USB disk.
What I want is a RAID1 setup of 2x 1TB btrfs.
Is this possible? How?

Motivation
The motivation for me to use RAID1 btrfs is because I just read an article talking about how such a setup would repair corrupted files automatically when the checksum on one volume fails.
Example of what can happen with a .jpeg
by just flipping one bit (I used vim for this. :%!xxd -b
