I did on proxmox. One thing I didn't know about ZFS, it has a lot of random writes, I believe logs and journaling. I killed 6 SSDs in 6 months. It's a great system - but consumer SSDs can't handle it.
I use a consumer SSD for caching on ZFS now for over 2 years and do not have any issues with it. I have a 54 TB pool with tons of reads and writes and no issue with it.

Did you have
atimeon?That doesn't sound right. Also random writes don't kill SSDs. Total writes do and you can see how much has been written to an SSD in its SMART values. I've used SSDs for swap memory for years without any breaking. Heavily used swap for running VMs and software builds. Their total bytes written counters were increasing steadily but haven't reached the limit and haven't died despite the sustained random writes load. One was an Intel MacBook onboard SSD. Another was a random Toshiba OEM NVMe. Another was a Samsung OEM NVMe.
