What are the latency characteristics like for io2? You’re mentioning near-local-nvme performance, but describing throughput (IOPS can be deceptive as they are pipelined, and as such could still give you 2ms latency at times).

Apparently io2 Block Express (I'm not sure what's the difference from io2) is capable of "sub-millisecond average latency"[0].
