I said no such thing! I also said I have a friend living in France that
burns up his cheesy flash drives in two months. Which I find is odd. As
I have never seen any that bad yet over on this side of the big pond.

What? No, I had 3 out of 20 drives fail within 20 years. That is just
under 7% failure rate. Google tested 100,000 drives and came up with a
very similar failure rate. They had a smaller percentage, but Google's
was only tested for 5 years and not 20 years like my study. So the
slight difference makes since.

Same holds true for cooking as well. I had worked for a time for a
company who manufactured food ingredients for other processed food
companies. And the same thing applies. And they threw out tons of
ingredients from time to time because a given batch didn't come out to
their high standards.

Same is true in component manufacturing. I worked in both fields. Where
did you get yours again?

Of course. Very few of them though. As the vast majority of them work as
they are suppose to. And if you are one of the unlucky ones, you just
take it back and get one that actually works.

My first laptop which costs $2000 back in '84. And that was a lot of
money for just 128kb of storage too. And I would have gladly paid 4
grand more for an extra terabyte drive. Or even just a gigabyte drive.
