This seems crazy low to me. AWS has default 3K IOPS and 125 MB/s throughput, meanwhile my Macbook Pro has 700K IOPS and 14.5GB/s throughput.

Is Amazon running on super outdated legacy networking?

SAN vs local. Local NVME (“instance storage“) on AWS is wicked fast too, but live and dies with the instance

in 2026 you can full the PCIe BW from remote storage at roughly the same latency as your local NVMe drive (hello NVMeoF).

your comment would have been valid 10 years ago, maybe.

Mind unwrapping this a bit more? I’m interested in iops heavy distributed caching and this seems like it unlocks some creative use cases there

Well, cloud providers aren't exactly known for performance so the comment is still valid and will be for quite some time still.
