PATA drives, and many but not all SCSI drives, are out

of the bathtub curve. This means that their reliability is now very
questionable. Contrary to popular belief, the MTBF figures in the
drive specifications do not give any information about expected
longevity of a single drive, so an MTBF of 200,000 hours does not mean
that a single drive is expected to last 22.8 years. The MTBF only
applies during the design life of the drive, which is usually five
years. Beyond that, you're living on borrowed time.
I fail to see what you're driving at. Most of my SCSI drives were
purchased new between, oh, 15-20 years ago and all have fewer than
1000 hours on them.
My situation can scarcely be unique.
