It's a very different story for SSDs. Those, you definitely do want to monitor in case your workload is burning through the rated write endurance faster than planned for. And reallocated sectors are usually not an urgent problem: a handful early in the life of the drive can be a normal consequence of vendors not aggressively testing (excessively wearing out) a drive before it leaves the factory, and a steadily increasing number as a drive approaches end of life is expected behavior. But SMART errors usually won't help you know when you're about to lose an SSD to a catastrophic firmware bug, which for many use cases is the more likely cause of death.
