I had an early ReadyNAS that was a champ for years. I wonder if the fact that it was based on SPARC had anything to do with its longevity.

From a risk assessment standpoint, I’ve seen my Time Machine backups corrupted much more frequently than I’ve experienced drive failure. Happened with both my Time Capsule and then my Synology RAID.

It’s a “nice to have” automatic backup, but not a primary backup destination for me.
