Mmm.. math error there.

The count is now an average of 34 erase cycles across all of the flash, after 76 power-on hours over 10 weeks or so. It's a notebook, and it's only powered on when I'm actively using it.

So, let's try that math again now:

10 weeks / 34 cycles = .29 weeks/cycle.
The flash chips are rated for 10000 cycles minimum,
so that's 10000 * .29 = 2900 weeks of use before it dies.

Which still works out to more than 50 years.

Another way is to do it by hours of use:
76 hours / 34 cycles = 2.2 hours/cycle,
so that's 10000 * 2.2 = 22000 hours of use before it dies.

Figure worst case of perhaps 40 hours of use per week,
that's 40 * 52weeks = 2080 hours per year.
At that rate, the drive would wear out
in 22000 / 2080 = 10.5 years of use.

I think I might have *one* other drive in the house that's survived 10 years, but it hasn't had nearly that amount of use.

Cheers
