Building a NAS is a large upfront cost but it’s worth it IMO. Giant HDDs are fairly cheap now and you can use cool filesystems like Btrfs to combat bit flips from cosmic rays and the like. I’m not sure I’d trust a dye based optical media, but there are apparently some archive quality 100 year BD-R. Most have a drastically shorter lifespan, though.

According to the Canadian Conservation Institute, which publishes a paper on media longevity, BD-R discs are expected to last between 5 and 20 years, depending on the material they are made out of. BD-RE, which is erasable Blu-ray, is estimated for 20 to 50 years while DVD-R and CD-R, which hold a lot less data, can last 50 to 100 years.
