Who are we?
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

Raid stopped being optimal now that btrfs and ZFS exist.
If you plan on doing matching drives ZFS is recommended
If you expect mismatched disks, btrfs will work.
If you are most worried about stability get a computer with ECC memory.
If you are most worried about performance, use SSD drives.
If you want a bunch of storage for cheap, use spinning disks (unless you exceed the 100TB capacity range)
