High I/O instances are storage optimized. Examples of this family are H1 (high disk throughput), I3 (high random I/O performance), and D2 (dense storage). EBS-optimized instances have exclusive capacity for I/O operations.

This question is focused on the portability of current features and performance only. Costs or managed services are not mentioned in the question.
