This is a question you'll get a lot of opinions on but no concrete
answers.  Most of the definitive studies done are at least 5 years old and
depending on who paid for the research, not all that trustworthy.  This is
one I cite regularly for those who ask:

I pretty much tend to ignore anything on any packaging from a vendor-
silver, gold, platinum... whatever... if you read the fine print, they all
say the same thing... if the disc is stored under OPTIMAL conditions and it
fails, they'll give you a new disc.  BIG DEAL... the disc isn't what you've
lost!!

For me, it's 3-5 years...tops would be 7.  Generally, applications used to
generate the data upgrade about that anyway, so you should open and refresh
the files anyway.

Also this guide gives you care and handling info for digital media-
