I was surprised that the Storm on Demand SSD instances didn't seem do better (really only ~2x as fast as spinning disks?). Turns out this is some weird bundle of benchmarks. I spun up a storm-ssd-3gb instance and ran bonnie++ on it. Results here: https://gist.github.com/2069845 https://gist.github.com/2069845 If I'm reading right, its ~868MB/s seq write (CPU bound) and ~594MB/s seq read (CPU bound). Not sure how to read the random IO results. The bigger instances would probably be faster still (more CPU). So the Storm on Demand SSD instances seem to be blazingly fast.
