Errors creating striped volumes in Win10 Disk Management

Specs: Windows 10 Ult, 12-core Xeon 64GB
I have upgraded one of my Mac Pros (late 2013) to run Windows 10 Ultimate on boot camp. It all installs fine and everything seems to be recognised. However, problems arise when trying to create striped volumes in Disk Management. I have 4x1TB SSDs in an OWC Thunderbay4 box connecting via thunderbolt2.

On the MacPro running Win8.1 it sees the discs and allows me to create a striped volume with no problem. On the Win10 box though it creates the volume and then cannot format it giving an error of "unable to complete format" and I am left with a RAW volume. Same problem if I try to make a mirror or spanned array although the drives format fine on their own. Storage pool works fine but I need the speed of the RAID0.

I have tried creating the RAID on the Win8.1 machine (which works) and then connecting it to the Win10 one. When I import the foreign discs though, the resulting discs are shown as RAW. I have put the discs into another thunderbolt box (Netstor) and I get the same problem.

All discs are initialised as MBRs (as usual) and I have also tried to do it on an iMac and a MacBook Pro running Win10 with the same error so it's neither the drive box nor the computer. I have also tried to format from the command line but that too results in Failed Format.

Any ideas?

I've checked out the alternate search links but none seem to help. Any other ideas?

I'm able to create striped volumes without issue, so the obvious questions are, "Can you use them as normal, non-stripped volumes in Win10," "Have you checked for driver updates for the thunderbolt2," and, "Are you sure you're not using one of the home versions of Win10?"
