Windows Storage Spaces

I have 5 2TB SATA drives set up in Windows Storage Spaces to provide a parity space. When the drives are formatted, they are 1.81TB each. I know that with parity you effector lose a drive's worth of space. But that should leave me with 7.24TB of space from a 9.09TB Storage Space.

 

But for some reason, Windows is telling me that I can only have a 6.03TB space with resiliency and if I increase it to more than that, then it goes over the 9.09TB allocation. I would rather just have it use the drives I have rather than overallocating the space. So somehow, I'm missing over 1TB of space. I know that I lose efficiency to the way that Storage Spaces stripes data across the drives, but it should still show the total capacity correctly.

 

Any ideas? I would swap to UNRAID if I had a spare 4TB drive to backup the Storage Space while I tore it apart
