Copied 699GB of data so far and the deduplication disk is 595GB so that's a 1.17 deduplication ratio - ~17% more disk space. Will carry on the robocopy (it stopped for some reason) to get to the total 937GB on the source disk.

Well, yes, 20% is still savings. As I understoud you are using Hyper-V VMs, and to be honest this is known that VHD are not the best files that are formatting. But I think it still can be tuned. The recommendations are:I received the extended trial license so was able to finish the copy (with 4k blocks & delete blocks enabled) and the overall deduplication ratio on an 800GB general-purpose file share was 1.19 which I'm saying is 20% between friends. The purpose of this trial was just to see what kind of ratio we'd get if we deployed and I guess a 20% saving is not to be sneered at.
Indeed it could and I'd equally I'd never recommend running StarWind or any software SAN virtualised. Fine for lab tests.As for the second issue: for me it more looks like Workstation issue. That is why we do not recommend to run StarWind on VMs.

I think the stability problem is a VMware Workstation issue as it happened several times. All I had to do was cleanly shutdown the VM and on start-up, VMware warned about consistency problems with the VMDK. Allowing it to fix it and then repairing the disk in the StarWind VM and all was well.
Whilst StarWind can obviously by run inside a virtual environment, I'd personally be happier with it running bare metal. Won't help performance putting in the virtualisation layer. Once again, for a lab environment, Hyper-V, XenServer or VMware V-Sphere ESX would all be even better than VMware Workstation.
