Three of my 6TB drives are showing SMART warnings. most options are backordered, and what's in stock is priced in a way that made me reconsider my cold storage approach.

That pushed me to run the BD-R numbers for my cold archive — about 40TB of media I access once or twice a year at most.

~$35/TB at current 25GB disc pricing. Panasonic rates some of their archival BD-R media for long-term storage, cited around 50 years under proper storage conditions.

But, I need to manage a large number of discs. BTW, Sony confirmed they're winding down consumer-grade recordable Blu-ray production. Drive availability is getting thin in some markets.

Is the best solution to combine NAS and optical? Curious what everyone here is doing for cold storage right now.
