If you do this it would be very interesting to see performance
figures for the following setups:
- btrfs with raid1 meta and data allocation
- mdadm raid1 on raw devices
- mdadm raid1 on dm-integrity (no encryption) on raw devices
- mdadm raid1 on dm-integrity (encryption) on raw devices
just to see what kind of performance loss dm-integrity and
encryption is going to impose.
After doing it, it would find a nice home on the Linux RAID wiki:
