Is it preferred to go on the temp drive D:? It seems like that's the case because it's faster HD, but wouldn't this space be lost in a reboot/VM move? Would the VMScaleSet re-install service fabric?

Service Fabric stores state on local, ephemeral disks, meaning that if the virtual machine is moved to a different host, the data does not move with it. In normal operation, that is not a problem as the new node is brought up to date by other nodes.
The cluster definition is on the C: drive, the state is on D:. The cluster definition will survive reboots. And because the state is stored redundantly, SF can provision new nodes with the state, provided there are sufficient operational nodes still running.

So in my ARM template it's set to D:\svcfab, that appears like it's installing the app/cluster definition to the D:? – Dave N Oct 29 '17 at 22:03

if you're talking about `"dataPath": "D:\SvcFab",`, this is about the data (the state). – LoekD Oct 30 '17 at 07:23
