Well that’s not quite fair. AWS guarantees performance for those instances (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/i2-instances.html#i2-instances-diskperf). They also guarantee their instances will fail sooner or later, with or without warning (at which point you will loose all your data unless you’ve been putting copies onto a different system).
