+1 to that

Spinning disks are inherently unreliable things.

We somehow expect them to last without fault for 5 years and lose sight
of the fact that if we don't switch them off that is 43,830 hours. How
many bearings out there in the world are built to last 50,000 hours at
bargain-basement consumer prices?

Aircraft, marine and earth excavation engines are made to that spec.
With a million buck price tag. Your machine machine isn't and drives are
in the same class as decent washing machines.

No-one makes a bad car anymore. Everyone turns out a dud occasionally.
s/car/disk/ is still true

Hans, don't take this the wrong way, but what you say doesn't mean squat.

Google has 1,000,000+ drives, I'll trust what they say after statistical
analysis.
Rack Space has a goodly number of drives too so I'll trust them as well.
I'll even trust my previous employer (an ISP with 10+ data centres) and
customers fitting every example of every drive out there at random. Our
tests (admittedly unscientific due to lack of controls) showed that
every brand and type was about as likely to fail as every other type,
excepting anomalies due to bad batches.

But your anecdotal once-off experience - doesn't mean anything
