Caching SSD on Invisible Memory PLUS caching HDDs on SSD?

Does it make sense to use the invisible memory for L2 cache of SSD AND to cache HDDs in L2 to this SSD?
It is working fine so far...

It will work but you're adding latency, you're flushing data out of ram and then right back in.
I'd suggest that you assign the HDDs the largest lvl 1 cache you wish to dedicate and don't use more then 60-75% of the SSD as a lvl 2 cache (SSDs slow down as they fill up).
