If SMART is going to lull you into a sence of security as to whether you should be vigilant with backups, you're better off without it anyway. My 2TB LS-Pro (LS-XHL) backs itself up with incremental backups nightly to an attached 2TB USB drive that cost me about $100. That's worth a lot more than SMART. SMART only predicts with a degree of probability. It doesn't guarantee.
