RAID vs. Software-defined storage (SDS)? (lemmy.world)

I got 4 20TB drives from Amazon around Black Friday that I want to get setup for network storage. I've got 3 descent Ryzen 5000 series desktops that I was thinking about setting up so that I could build my own mini-Kubernetes cluster, but I don't know if I have enough motivation. I'm pretty OCD so small projects often turn into big projects.

I don't have an ECC motherboard though, so I want to get some input if BTRFS, ZFS, TrueNAS, or some other solution should be relatively safe without it? I guess it is a risk-factor but I haven't had any issues yet (fingers crossed). I've been out of the CNCF space for a while but Rook used to be the way to go for Ceph on Kubernetes. Has there been any new projects worth checking out or should I just do RAID and get it over with? Does Ceph offer the same level of redundancy or performance? The boards have a single M.2 slot so I could add in some SSD caching.

If I go with RAID, should I do RAID 5 or 6? I'm also a bit worried because the drives are all the same so if there is an issue it could hit multiple drives at once, but I plan to try to have an online backup somewhere and if I order more drives I'll balance it out with a different manufacturer.

It's a lot cheaper in the long run to do an off site backup rig and just put it at a friend's house if you can. Google will be expensive.

I don't have any friends really 😥 and the unlimited storage with Google Workspace was $25/mo. I think it will cost me about $125/mo. now to get enough pooled storage with Google, but it is doable at least in the short-term. I guess I need to make some friends with fiber connections.
