Say I have a 120GB SSD and a 2TB volume from a portion of a larger RAID6 array. I would like to spin up a Windows Server VM for purely low-impact personal use that employs a large data store in some fashion. Which would be a better practice: (a) Separate the OS and data drives, physically, by giving the SSD the C:\ drive and the 2TB RAID the D:\ drive, or (b) place the VM completely within the RAID array and disregard the SSD?
It strikes me that (a) might offer more performance and a negligible space increase while (b) might improve fault tolerance, since the SSD is not backed up in this scenario.
