It's good to periodically consolidate onto a new mirrored pair of reputable spinning rust with ZFS or another filesystem that can automatically monitor for bitrot, even if you keep the old ones around (drive reliability economics varied over time as vendors consolidated).

Gives opportunity for sorting archives into tiers of importance based on current perspective. Content with highest ratio of importance/size can be stored on enterprise-grade SSD.

The best motivation for keeping healthy archives is to use them :) It's worth finding offline OSS/paid software to help categorize/search/browse archives. Upcoming offline LLMs should also help.

Tailscale on Apple TV (and other devices) can be an exit node for remote streaming access to archives on home networks.
