So what for low grade SSD´s?

[ororokorebuh]

Hello, I have small server with 192GB RAM and nvme where proxmox is installed.

I have also 4 SSD´s on SATA ports. Two are 512GB and another two are 1TB. I would like to mesh them together like in ZFS (raidz) but as I know ZFS will destroy low grade SSD quite fast. So I would like to use LVM Thin (to be able to do snapshots), but it seems I can´t join those discs or create something like raid or mirroring between them...

My goal is to run Windows server in VM. This server will be migrated from physic server which has now two raids so like two physical discs. I will create VHDX and migrate it to QCOW2. SO I think I will have one big storage from all discs or 2+2.

Please could someone point me what is the best way to go?

Thank you.

With different-sized disks, you could have 2x zfs pools. 1 mirror for the 512s and 1 mirror for the 1TBs.

Or you could make it 1 big "raid10 equivalent" pool with mirror 2x512 + mirror 2x1TB, but your I/O won't be balanced.

ZFS wearout is mostly a concern for Proxmox boot/OS SSDs.

So you really think for ADATA SU650 and Patriot P220 is ZFS not a problem if I will use them for VM?
I could also have RAIDZ (for all SSD´s together) with ZFS right? Is it better or worst option than your recommended mirror?
