Still kicking around this idea and didn’t see it addressed in any of

If one made an all ssd pool, would a log/cache drive just slow you
down? Would zil slow you down?
I would guess not, you would still be spreading your IOPs. I haven't
tried an all SSD pool, but I have tried adding a lump of spinning rust
as a log to pool of identical dives and it did give a small improvement
to NFS performance.
