  • I recently upgraded three of my proxmox hosts with SSDs to make use of ceph. While researching I faced the same question - everyone said you need an enterprise SSD, or ceph would eat it alive. The feature that apparently matters the most in my case is Power Loss Protection (PLP). It’s not even primarily needed to protect from an possible outage, but it forces sync writes instead of relying on a cache for performance.

    There are some SSDs marketed for usage in data centers, these are generally enterprisey. Often they are classified for “Mixed Use” (read and write) or “Read Intensive”. Other interesting metrics are the Drive Writes Per Day (DWPD) and obviously TBW and IOPS.

    At the end I went with used Samsung PM883.

    But before you fall into this rabbit hole, you might check if you really need an enterprise SSD. If all you’re doing is running a few vms in a homelab, I would expect consumer SSDs to work just fine.
