you might consider storing in amazon s3 ..its highly durable and cheap and wont suffer from local hdd failure. it probably wont be sold in the near future.
For the sake of completion, do both. A NAS box with a S3 or Glacier backup routine will do it.
Now, I'm on the cheap side, but I find AWS expensive compared to other backup services like backblaze. Perhaps it's the backup services that are overly cheap, I don't know, but I'd love to have a cheaper service available for backing up from a NAS (backblaze seems to be pain to setup on a NAS). I'd be OK with major inconvenience on retreaval, as long as it's cheap to backup.

Glacier is $10/month for 1TB. For highly durable long-term storage, that is stupid cheap.
