What is the best Hyper-V disc configuration?

I have a Server with 300Gb in RAID1 and 4TB in RAID10
I have installed Windows 2016 Server Std which I shall use as the Hyper-V Manager. This has been installed on 32Gb of the RAID1
I now have:
Drive C: 32GB (RAID1)
Drive D: 2TB (RAID10)
Drive F: 250Gb (RAID1)

I intend to build two VMs
When I build the VMs, should I installed the VM image on Drive F: and the VM discs on D: to give the best performance?

What do you mean under "VM Image"?
Anyway RAID10 is faster than RAID1
So you can use RAID1 for VM that do not need good performance.

By the way, you use sas or sata HDDs?

When I purchased the server, Dell sales told me that I should have a RAID1 and a RAID10 array. The RAID1 should be used for the Operating Systems and the RAID10 for the data because this would improve performance dramatically. It sounded like a compelling reason at the time so 2 x 300G drives in a RAID1 were added to the spec.
Now that I come to build a couple of VMs, I can't quite see how to implement this.
In the Hyper-V settings I can specify the default location for Virtual Machines and Virtual Hard Discs. I assume that the Virtual Hard Discs should be located on the RAID10 array but should the Virtual Machines be located on the RAID1 array? Is this what Dell were referring to I wonder?

Personally I move the default folder to anywhere not on the system drive (where the OS lives) This for me keeps everything organized in a defined structure and a consistent area.

I first create a directory on the drive I want i.e. Hyper-V then copy the contents of the c:\programdata\Microsoft\windows\Hyper-V folder and in hyper-V tell it to use that location

That is unfortunate that Dell Sales made such a claim. :(

No, they were talking about setting up a RAID 1 array on the RAID controller composed of the indicated two disks. Then, create a RAID 10 array of the rest of the disks. This would all be done at the RAID Controller BIOS level.
