Hard Drive RPM/Cache mixing

[Tomek]

Hello internet peoples

I've been doing a lot of research on ZFS and joined your community a few days back. Very nice guides and how-to's :). Those have guided me on the type of build I'll be working on but I have a few questions that I couldn't find the answer to. Hopefully you guys can help. This would be a RAID-Z / RAID-Z2 config.

Can you mix various speed HD's in your pool? Can you mix various cache HD's in your pool? Obviously I'd grab HD's that are very similar at first build/setup but what if down the few years I lose an HD and the only choice I have is a 10k rpm drive with 128mb cache?

That makes sence. So it should work, but it will match the weakest property/s.
