A "bathtub curve", they call it. Lots of infant deaths, and a bunch at very old age, but pretty stable in between.

I just think hard about how delicate the mechanical stuff is inside one of those, particularly when there are 8 platters stuffed inside an 8TB drive. Very very tight tolerances. The parking mechanisms seem to rely mainly on friction to hold the heads in place -- there's no mechanical interlock there.

Then I think about the various parcel delivery experiences I've had and witnessed.. especially the UPS guys that Amazon is so fond of over here.

My own (mechanical) hard drive failures ceased when I stopped receiving drives from remote suppliers. Now I have a glut of drives, as I replace long-lived 3TB/4TB models with new 8TB units. A Good Problem to have, I suppose!

Recently, I suspected one of the Seagate 8TB units was dying, but managed to trace the fault to a cracked SATA connector on the little red cable instead.
