I have multiple consumer grade drives made in 2008-2010 that have been used a lot and have more than 7 years of recorded time of the head flying over the platters and they still work fine. Some with zero reallocated sectors and others with 1-10 in the last decade. But the number hasn't changed for 3+ years in any drive so it doesn't bother me. Before you say it, of course I keep backups of everything. That's why I still use decade old hardware without much worry.
