OK gets more interesting.

Changing my Adaptec Mode to be RAID hide RAW and then creating the RAID0 of 2 Disks ( 6 Pairs ) then was unable to use the Volumes directly. However using the Software RAID was perfectly able to use the HW RAID Volumes to create Software RAID volumes using 2 of the HW RAID Volumes.

As such clearly the new Soho CAN work with the HW Raids but appears to just be being actively blocked now unlike previously with the Lite version.

Definitely a step backwards compared with Lite.
