I run used disks with tens of thousands of power on hours. Yes the risk of each disk dying is higher but only marginally and the cost is dramatically lower. To avoid data loss when they die, I have functioning backups. This system is working really well for me.

What’s the best way to make an offsite backup for 42tb at this point with 20mbps of bandwidth? It would take over 6 months to upload while maxing out my connection.

Maybe I could sneakernet an initial backup then incrementally replicate?

SSDs have a write lifespan. Once you write ~400TB or whatever it’s rated for on a consumer SSD it dies. HDDs can take a lot more writes before dying.

some kind of api aggregator could probably work but i don’t think there is one yet
