Don’t use flash drives, they’re susceptible to the same issue as memory cards, especially when not powered on for a long time.
Check out blu-ray m-discs. They’re ceramic discs that are physically etched on burn (you’ll need a compatible burner). Once burned, any blu-ray drive can read it. They have theoretical lifespans of over 100 years. If you go this route, I recommend storing a blu-ray drive (or two) with your discs. This is exactly what I do for important documents.
Tape is another great option, however it is more sensitive to environmental factors such as temperature and humidity. I also use this for backups.
Hard drives can have bit rot, especially if not powered for long periods. You can definitely still use them as part of your backup solution, but I’d put them into an array or pool of disks which checks for corruption or sync issues. Unraid, for example, can do this. TrueNAS has options for this as well. It’s a rabbit hole to get into them, but if you want to get serious about backups (such as setting up 3-2-1 or even 4-3-2 backups), you’ll probably want something in the middle that manages everything. Just keep in mind that RAID (or Unraid’s array protection) is not a backup on its own. You can use it as part of the solution, but do not ever rely on RAID to protect your data.

321 is what I’ll do. Do you think PenDrives are good?
As in the USB sticks? Those use flash memory, and in my experience have worse durability than a lot of SD cards.
Really? I’m really interested, because I had great experiences with those.
Yeah, especially if they are written to a ton or left sitting on a desk for months, they’re very likely to lose data in my own experience.
