ZFS absolutely does not require them in any way.

Who said it does? Also regarding Proxmox:

Looking back at your original post, why are you using Proxmox to begin with for NAS storage??

For ZFS what you want is PLP and high DWPD/TBW. This is what Enterprise SSDs provide. Everything you’ve mentioned so far points to you not needing ZFS so there’s nothing to worry about.

Yes I’m specifically referring to your ZFS pool containing your VMs/LXCs. Enterprise SSDs for that. Get them on ebay. Just do a search on the Proxmox forums for enterprise vs consumer SSD to see the problem with consumer hardware for ZFS. For Proxmox itself you want something like an NVME with DRAM, specifically underprovisioned for an unused space buffer for the drive controller to use for wear leveling.

ZFS is great, but to take advantage of it’s positives you need the right drives, consumer drives get eaten alive as @scrubbles@poptalk.scrubbles.tech mentioned and your IO delay will be unbearable. I use Intel enterprise SSDs and have no issues.
