I used 1.1 because that's also where filesystem metadata usually goes
and therefore one might hope that the presence of the md metadata
would prevent accidental identification of a raid volume as containing
a filesystem.

I like 1.2 because if you happen to write an MBR or something to the 
drive, you don't lose the superblock.

With 1.2 I can also take the drive from a 3ware hw-raid (single drive in 
3ware bios) and put in a non-3ware (because the 3ware stores the 
superblock at the end, so when you put it in a non-3ware the end has now 
changed).
