EC2 (local) instance storage

It's well documented that fresh EBS volumes keep track of touched blocks; to get full performance on random writes you need to touch every block first. That implies to me that they don't even allocate the block on the back end until it's written to.
Not sure how instance storage initialization works, though.

As you say, instance local storage is different.
