Yes just noticed that, since you pointed it out, however I must have had the latest date on the threads back to front!
Did you ever find an updated answer to this? I'm thinking this might be even more interesting now that we're looking at FreeNAS 10 and docker containers on the horizon. At least for mid- to low-end users like me sitting on a main pool consisting of spinning metal looking for a bit more snappy jails or VMs.I am bumping this to see if the current logic behind the answer has changed now that we are on version 9.10.
Would it be a reasonable thing to install some configuration of solid state drives to create the "jails" root folder?
I don't think anyone is looking at this thread any more.. It was started back in 2012 after all...Did you ever find an updated answer to this?

I used a single SSD for my original Jail. A mirrored pair of SSDs should be very fast, but modern ones have enough ware endurance that you will probably not use them up before you are ready to move to new hardware.Yeah, I'm pretty much already decided on separating my jails/VMs from my main pool. Leaning towards two SSDs in a mirror with regular backups to the main pool. I can't imagine there being any real downside except for SSD lifetime and in my setup the SSD write number limitations will not be an issue.

I installed my Jails to a separate pool that is made of 1TB drives in a mirror. The main storage pool is all 2TB drives in RAID-z2 and I am not sure which pool is faster.
don't mix different technology into one pool. ZFS is not able to handle that efficiently. If you need SSDs for your VMs/jails make a dedicated SSD poolGenerally it is accepted, that everything on one pool is most optimal. But I was wondering, what are the benefits of having jails/plugins/vms on separate pool, tailored whether of mirrored SSDs or HDDs as You have?
Experienced any downsides?
Thanks, my post from 2016 really brought back memories.Well, I am looking at it right now :). I have a pool of 8 2TB drives in raidz2 and practicaly can have all the datasets inside, including the one for plugin jails. There are some nice quirks and tweaks to optimise a non-optimal set up of 8 drives (due to lost space etc.), but I was thinking going back to more traditional 6 drives raidz2 configuration and employ the rest of two drives for something more efficient, maybe of this sort.

Did You ever actualized Your decision? If so, did that went well?Yeah, I'm pretty much already decided on separating my jails/VMs from my main pool.
