[Web4lib] pcs running more slowly as time passes

[Thomas Edelblute]

Once upon a time, I had a paper from Intel that graphed out the hardware failure rate for PCs.  It was pretty flat for the first three years, then spikes upward starting with the fourth year of operation and continues going higher after that.

Of course, I also remember from my basic electronic instruction that 7% of all electronics fail out of the box.

I agree with Jon. Modern consumer level drives are pretty much junk
designed to deliver incredible specs for a bit, then die. Harkens to
cars in the 60's -- planned obsolescence.
