Hear me out (RaidZ1 pool as array with backup actual array on the same machine ??)

[Martsmac]

Hi all , I'm just spitballing here but I have a question. Would there be any benefit to having a zfs RaidZ1 POOL configured to store all my array data but in a pool as opposed to on the array (and thus the shares be on it) then just have a regular old unraid ARRAY running sperately to hold backups of said data that's on the pool. 

 

In my tiny brain this would allow my pool to get the faster read and write speeds of the RaidZ1 pool, but also have a backup sitting in the actual array with a parity disk (or 2).

 

Genuinely interested to see if this would work I just saw a video where a guy was getting really good write speeds from a RaidZ1 pool of spinners (way in excess of what I get from mine in my zfs array). 

 

I understand that having the backup drives physically in the same machine is not a sound backup strategy , but at least it would be on its own array!??

 

Thanks ..
