One good example use case would be running distributed NoSQL / KV stores. Running say a Riak KV cluster or an image caching and processing service. Both of these would probably be best using SSD EBS's to be able to bring the data storage and computing closer together rather than using RDS or similar, which in certain use cases it can be significantly faster due to less network calls and latency. As an example setup, Rancher has a plugin to allow using docker data volumes from EBS volumes. It handles the naming, attaching the drives to the EC2 instance, etc.
