I run a Proxmox cluster with 2x Dreamquest pro, each with 2x10TB had in an IcyBox, plus an external Raspberry Pie with a 12 TB disk for backup.
The disks are refurbished to keep the costs down but run in a mirror setup. So if one fails, I’m fine. I use an old laptop as a 3rd node and the main nodes replicate their load, so I‘m fine even when one node is dead.
Almost the same way I used to use Twitter innthe early days:
Works really well for me and even though I only have half the amount of followers I had on Twitter, I have more high quality conversations and less trolls.
