I am not too worried about bad performances.
I am afraid to get paged one night because the 50+ TB of the storage 
cluster are gone followinf a bug/crash...
It would take days/weeks to set it back up from the backups.
If we were rich, I guess we would have two (or more) "geo-replicated" glusters and
be able to withstand one failing...
I would like the same trust level that I have in RAID.
