About 30 years using computers, a little over 20 being paid to do it. I've had two fail outright (one internal, one external) and a couple others develop errors that I noticed (one because I finally started using ZFS on my bulk-storage machine and it's very good at telling when a drive is misbehaving, the other, SMART caught, years ago) so they had to be replaced. All were spinning rust. Maybe 50 drives total, over my computer-using life, counting those in game consoles and ones in work machines that were assigned to me. Including SSDs. Give or take 10. With the experience of the last 3 or so years of using ZFS, I'd bet most of my "still working" drives over the years were erroring and losing data by the time I replaced them, and I just didn't know it.
