Good to know - I was contemplating doing this with some spinners in it
for bulk storage, as I have some 2tb's left over now. Peeling off some
of those 512's to cache for the spinners might make them more useful so
I don't have to burn space on the ssd's exclusively.
How much ssd do you end up using per tb of space? I don't want to lose
a lot of space on the ssd's, and plan to run the base os and usr/home
space from ssd, really I just want to back vm space if necessary on them.
The other thought was just using memory as a tmp cache with ramdisk.
I'm going into it with 128gb as only having 32 has been causing me
issues lately. If the caching doesn't require more than say 32gb, might
be interesting to try caching to tmpfs instead. Been a notion of mine
to try for grins.

I still want to try dmraid-1 plus nvme drive with lvmcache.
PS SSD based lvmcache has been running well for me.
