Absolutely. I've looked at the SMART data of easily over 1000 drives. Many of them ok, many of them with questionable health, many failing and many failed. The SMART data has always been a valuable indicator as to what's going on. You need to look at the actual values given by tools like smartctl or CrystalDiskInfo. Everything you need to evaluate the state of your drives is there. I've never seen an HDD fail overnight without any indication at all.
