I use spinning disks for archival backups. It's been reported that SSDs aren't reliable for that. Hard disks also are questionable for long term storage, which means I rotate them often, but still.

Anecdotally, USB sticks I throw in a drawer tend to go bad after a few years.

I'd still love to replace all the spinning disks with SSDs, though. Faster, smaller, less power, less fragile, silent, what's not to like? Hope the longevity issue gets better.
