When setting up my Hyper-V clustered nodes, each node has (2) RAID 1 525GB SSD drives for the Server OS and is attached to shared storage. I know the Allocation unit size for all the shared drives should be 64K for SQL Server and for VHDx files. However,
what about the Allocation unit size for the OS drives on the Hyper-V host OS and the VM OS on the VHDx. Are they okay to leave with the default or should they be 64K too?
