Oh yeah, I don't think the way I went about it was necessarily the most cost effective. I bought half of them on sale one year, didn't get around to setting things up, then bought the other two a year later on another sale once I finally got my server put together. I got them before I had my current plan in place. At one point I thought about having more services in a Kubernets cluster or something, but dropped that idea

Also agree, RAID isn't a replacement for a backup. I have all my important data on my desktop and laptop with plans for a dedicated backup server in the future. RAID does give you more breathing room if things go wrong, and I decided that was worth it
