It sounds like SimpleDB runs on EC2, meaning it can't do anything that you couldn't build yourself on EC2. If you replicate data across enough EC2 nodes you can get durability (at the cost of complexity and high MTTR).
EC2 doesn't give you durability, and S3 doesn't give you speed. SimpleDB gives you both.
