That's why I prefer v1.2 superblocks, it's stored safely away from MBR
overwrites, but still not at the end.
Quoting "man mdadm"
1, 1.0, 1.1, 1.2
Use the new version-1 format superblock. This has few
restrictions. The different sub-versions store the superblock at
different locations on the device, either at the end (for 1.0), at the
start (for 1.1) or 4K from the start (for 1.2).
I consider v1.0 and v1.1 as dangerous because of why you wrote, as well as
accidental MBR writes.
