Anecdotal: I've been into pc's for 30 years. Each failed harddisk I had over those 3 decades was announced in advance by increased sounds, lowered performance and SMART warnings. In all cases I was either capable of retrieving all the data before the thing died, or at least managed to recover most of it. With SSD's, the failure was always sudden, zero warning, and resulted in 100% data loss. My most important files live on traditional spinning hard disks and will continue to do so (and backups, of course). Knock on wood.
