Re:SSDs Have Become Fast, Except in the Cloud

Ebsv5 and Ebdsv5 somewhat uniquely provide the highest possible storage performance right now in Azure, partly because they support NVMe controllers instead of SCSI.
However, the disks are still remote replicas sets as someone else mentioned. They’re not flash drives plugged into the host, despite appearances.
Something to try is (specifically) the Ebdsv5 series with the ‘d’ meaning it has local SSD cache and temp disks. Configure Postgres to use the temp disk for its scratch space and turn on read/write caching for the data disks.
You should see better performance, but still not as good as a laptop… that will have to wait for the v6 generation of VMs.
