Ideal is to do not use VMs at all. And not Windows. Also 1 disk/1 node and not all at once, but when the previous almost full or at least vetted.
However, you are using what you have now.
If you going to reconfigure, please do not use VM, the performance will be bad especially on NTFS and especially VMWare.
Use docker instead if the host is Linux. If the host is Windows then docker is not a best option, since it will be in the Linux VM too, but at least you may run several nodes there without much of issues or you may use Win GUI Storj Node Toolbox to run several Windows services instead.
