simple storage = NTFS or exFAT
other reasons = ZFS or ext4

Uh, I may be really ignorant, but AFAIK RAID isn't a file system? You still have to choose that...
I just use NTFS, haven't really had any issues. I know it's not state of the art, but good enough for what I do. And I archive on DVD anyway. Real old-fashioned guy, heh ::)

yes, but anything under raid1 wouldn't make it better though, so yeah slap anything under raid1 is what i meant.

Well, I understand what you mean, that RAID is a good protection for file corruption, but if your file system messes up, it does not matter if you use non-RAID, RAID 1, or RAID 5; it's not the same level of technology. RAID protects against hardware failure, a disk going bad, while good file systems will protect you against other types of corruption, like power fails during write, etc. But of course there is some overlap.

but last time i checked, except the old fat file system though, have good enough managing for the other things to matter.
what matters on file storage is sheer capacity on top of hardware longevity, nothing else would matter really.
power outage during write times is another problem and not exactly a problem with a file storage, and you should have an UPS already imho.

I'm not quite sure I follow. The OP's question was about what file systems that are good for archiving. Thus, if they are safe. Capacity should not be an issue; as far as I know no file system has ever been so bad that it uses a lot of unnecessary space. What a good file system does, is that it helps protect against "soft" errors, i.e., data corruption due to timing errors and similar. Programs opening files for for transactions and messing things up, or the PC being shut down in the middle of things. Completely different from HW fails, which nothing but storage redundance can protect you from.
A UPS may be nice, but it still will not protect you against a poor file system mishandling a half-assed file transaction from a frozen program or PC.
Overall, I still think most modern file systems and OS will handle this decently, though :)

The OS will need to handle problems in case of incomplete writes.
