I've had RAID 6 fail. It should be extremely rare, but isn't. And at AWS's scale, It's not hard to imagine servers going offline regularly. Ephemeral storage as a policy makes sense to me in the sense that you can separate out that what's important from that which is ephemeral, and provide cheaper storage than a more HA solution like ganeti.
