Yup, and for performance, you would RAID Stripe a bunch of EBS volumes together. But sometimes you'd get a volume on a noisy neighbor, and its performance would be terrible.

Where I worked at the time, I wrote some Chef tooling that would hdperf the volumes it provisioned, and if some weren't any good it would provision more until it got 8 good ones. Only then would it RAID them together, then deprovision the bad ones.

Now they have provisioned iops, and I haven't seen a slow EBS volume in a decade.
