I’ve posted a few days ago, asking how to setup my storage for Proxmox on my Lenovo M90q, which I since then settled. Or so I thought. The Lenovo has space for two NVME and one SATA SSD.

There seems to a general consensus, that you shouldn’t use consumer SSDs (even NAS SSDs like WD Red) for ZFS, since there will be lots of writes which in turn will wear out the SSD fast.

Some conflicting information is out there with some saying it’s fine and a few GB writes per day is okay and others warning of several TBs writes per day.

I plan on using Proxmox as a hypervisor for homelab use with one or two VMs runnning Docker, Nextcloud, Jellyfin, Arr-Stack, TubeArchivist, PiHole and such. All static data (files, videos, music) will not be stored on ZFS, just the VM images themselves.

I did some research and found a few SSDs with good write endurance (see table below) and settled on two WD Red SN700 2TB in a ZFS Mirror. Those drives have 2500TBW. For file storage, I’ll just use a Samsung 870EVO with 4TB and 2400TBW.

SSD	TB	TBW	€
980 PRO	1TB	600	68
	2TB	1200	128
SN 700	500GB	1000	48
	1TB	2000	70
	2TB	2500	141
870 EVO	2TB	1200	117
	4TB	2400	216
SA 500	2TB	1300	137
	4TB	2500	325

Is that good enough? Would you rather recommend enterprise grade SSDs? And if so, which ones would you recommend, that are m.2 NVME? Or should I just stick with ext4 as a file system, loosing data security and the ability for snapshots?

I’d love to hear your thought’s about this, thanks!
