What's the failure rate of EBS versus having direct access to physical disks? My guess is that at scale, it's probably similar.
Although you would hope that the storage components of AWS's cloud were highly reliable, I think the main benefit is not single instance reliability but being able to recover faster because of quickly available hardware.
