Bad things are going to happen if you loose a complete chunk of your filesystem. I think the current state of the world is that you should assume that realistically you will be looking to your backups if you loose the wrong 2 disks in a raid1 or raid10 array.
Which is a very good reason to have at least one hot spare in any RAID setup, if not 2.
RAID10 also statistically has a much better chance of surviving a multi drive failure than RAID5 or 6, because it will only die if two drives in the same pair fail, and only then if the second one fails before the hot spare is rebuilt.
