Thanks. It appears that putting SSD in "Default group" and moving all 
spinning HDDs to another storage group should do the trick.

Disk selection algorithms are all based on space usage and my SSD will 
fail next to large HD pool that I have as 12TB RAID. So, your first 
method is more suitable, I think. I will copy overnight between SSD and 
HD making sure that I leave more recent recordings in the SSD and still 
leave enough space to record.
