Then you will have same problems but now you can bother manufacturer about it!
Also unless there is something horribly wrong about how often data is written, that SSD should run for ages.
We ran (for a test) consumer SSDs in busy ES cluster and they still lasted like 2 years just fine
The whole setup was a bit of overcomplicated too. RAID10 with 5+1 or 7+1 (yes Linux can do 7 drive RAID10) with hotspare woud've been entirely fine, easier, and most likely faster. You need backups anyway so ZFS doesn't give you much here, just extra CPU usage
Either way, monitoring wait per drive (easy way is to just plug collectd [1] into your monitoring stack, it is light and can monitor A TON of different metrics)

even some hacked setup with 2 way sync is better. The dumbest (but still somehow the least problem in their architecture) I saw was running [1] syncthing on few servers and just syncing everything and hoping conflicts won't happen...
Like, I did it, but I wouldn't recommend it, restarting NFS server is gnarly, HA support on OSS side is... not really there last time I checked, and overall PITA.
