Good reason to have proper backups in place
Backups for the Cloud, which is a backup. Yes, backups of backups. Lessons I've learned the hard way over the years.
In a domestic environment, cost becomes your limiting factor, depending upon your individual financial circumstances.
All failing drives I had were failing in the first week. Those that didn't fail in the first week all ran for years
In the world of electronics, that has always been a truism. Going back 40 years ago, Military Specification integrated circuits were "burnt in" for a specified period. From memory, something like 1,000 hours.
In other words, depending upon the IC, it was put through its paces doing reiterations for 1,000 hours. Failure rate those days was around 3% from memory. It would be much less today with modern fabrication technology.
An interesting topic for Geeks - dead boring for the average person in the street.
The olden day joke went something like: "Did you know your 747 Jumbo Jet is controlled by recycled, used components? Even critical medical instrumentation which keeps you alive in hospital".
In theory, barring other external catastrophic events, integrated circuits should be good for a nominal 1,000 years after burn in.
I had a friend who worked with a molecular microscope [Electron Microscope]. One day in the Electronics Group we all belonged to, we were arguing over the necessity to ground yourself when handling modern CMOS integrated circuits. One school of thought argued it was essential, another argued it was pointless and not necessary because they never saw any ill effect on the circuit.
Our friend posted two molecular photographs to the Group. One was of a perfect undamaged transistor embedded within the IC. The other was an identical transistor, but from an IC where the pins had been touched by human hands and the static electricity within our bodies. Both IC's had performed perfectly - the latter had chunks chewed away from the molecules. As our friend asked: Would you place your life in the hands of that transistor when next flying in a 747 at 6,000 metres up in the sky?
That killed off that discussion.
Sorry for diverging, but remember that story the next time you pick up a new motherboard in your hands. Static electricity in your body? I can give you a simple, inexpensive test to prove it. Not a bad party tricks as well. You need to be able to buy a cheap NE-2 Neon Bulb though.
