How Long Can You Store CDs and DVDs and Use Them Again?

I have read on internet that Life expectancy of USB Flash memory under
the recommended storage conditions is around 10 years.

But i don't think that USB flash memory can replace DVD-R discs that
should have a life expectancy of 100 years to 200 years or more.


Please read the following:

"Manufacturers tend to use this premise to estimate media longevity.
They test discs by using accelerated aging methodologies with controlled
extreme temperature and humidity influences over a relatively short
period of time. However, it is not always clear how a manufacturer
interprets its measurements for determining a disc's end of life. Among
the manufacturers that have done testing, there is consensus that, under
recommended storage conditions, CD-R, DVD-R, and DVD+R discs should have
a life expectancy of 100 to 200 years or more; CD-RW, DVD-RW, DVD+RW,
and DVD-RAM discs should have a life expectancy of 25 years or more.
Little information is available for CD-ROM and DVD-ROM discs (including
audio and video), resulting in an increased level of uncertainty for
their life expectancy. Expectations vary from 20 to 100 years for these
discs."
