Curious if you tried this on an EC2 instance in AWS? The IOPS for EBS volume are notoriously low, and possibly why a lot of self-hosted DB instances feel very slow vs similarly priced AWS services. Personal anecdote, but moving to a a dedicated server from EC2 increased the max throughput by a factor of 80 for us.

Did you try to compare that to EC2 instances with ephemeral nvme drives? I'm seeing hdfs throughput of up to several GB/node using such instances.

Got burned there for sure! Speed is one thing but the cost is outrageous for io heavy apps! Anyways I moved to lightsail which doesn’t have io costs paradoxically so while io is slow at least the cost is predictable!

You can use locally attached SSD instances. Then you're responsible for its reliability so not getting all the 'cloud' benefits. Used them for provisioning own CI cluster with raid-0 btrfs running PostgreSQL. Only backed up the provisioning and CI scripts.
