true. I just assumed that anywhere it matters one would use gmirror.
As for myself - i always prefer to put different manufacturers drives for 
gmirror or at least - not manufactured at similar time.

2 fails at the same moment is rather unlikely. Of course - everything is 
possible so i do proper backups to remote sites. Remote means another 
city.
