I guarantee you that when you create a 100GB EBS volume on AWS EC2, you don't get 100GB of storage preallocated. AWS are probably pretty good about not running out of backing store, though.
Some db folks (used to anyway) advise dd'ing to your freshly attached devices on AWS (for performance mainly IIRC), but that would help prevent some failure scenarios for any thin provisioned storage (but probably really annoy the admins' thereof).
