  • Since you mentioned MLC, maybe you have some suggestions for eg used server grade disks? Would the Rpi be able to run something like the Intel datacenter SSDs eg S3700? The power loss protection is really something I would like to have, especially in a homelab scenario. Or any other notable MLCs with larger capacities? I am having trouble finding a good list sorted by max potential storage.













  • Running ZFS on consumer SSDs is absolute no go, you need datacenter-rated ones for power loss protection. Price goes brrrrt €€€€€

    I too had an idea for a ssd-only pool, but I scaled it back and only use it for VMs / DBs. Everything else is on spinning rust, 2 disks in mirror with regular snapshots and off-site backup.

    Now if you don’t care about your data, you can just spin up whatever you want in a 120€ 2TB ssd. And then cry once it starts failing under average load.

    Edit: having no power loss protection with ZFS has an enormous (negative) impact on performance and tanks your IOPS.
