[mythtv-users] Managing storage groups intelligently

I come from mythtv 0.27/0.28. So, I apologize if this is already handled 
in later versions.

Is it possible to prioritize storage groups when recording? I plan to 
add a 1TB SSD to the storage groups and would like recordings to choose 
that over spinning disk whenever possible.

If possible, I like to try this after the above is resolved. Manually 
move files between SSD and spinning disk (both are storage groups) to 
keep only recently created/accessed file in SSD and also make sure at 
lease 100GB space is left for any new recording. I will do this using 
overnight cron job.?? Since mythtv finds recorded programs as long as 
they are present in one of the storage groups, file moves should not 
affect look up for media files.?? Do you see issue with my approach?

Yes, I already investigated bcache/dmcache/lvmcache etc., and was 
advised that they are either overkill or unreliable or ineffective in 
mythtv environment.
