The issue with all AWS storage is that storage bandwidth eats your network bandwidth. And there are not-great documented multi-level throttles and bottlenecks involved in that.

Especially in the "Up to X per second" networking instances, which is basically all of them except the huge ones.

The activation of throttles is NOT well exposed in metrics, nor is bursting amount or detecting if bursting is occurring.

It is all somewhat shady IMO, with AWS trying to hide problems with their platform, or hide that you're getting charged in lots of sneaky ways.

Most instances are EBS optimized, and have dedicated bandwidth for EBS, optimized stack etc [1].
