You are designing a pooled AVD host pool that uses a golden image from Azure Compute Gallery. All user state is redirected to FSLogix profile containers on Azure Files, so the session-host OS disks contain no persistent data. Management wants to minimize per-VM storage cost and reduce OS disk read/write latency for these stateless session hosts, and they accept that reimaging replaces the OS disk. Which OS disk configuration should you choose for the session hosts?
