Howdy Sean,

SD> Tapes, on the other hand, when cared for properly, can last decades.

No they don't.  Just like music cassettes the magnetic information
migrates between the rolled up tape layers.

In this regard CDs and DVDs are better but they aren't perfect either.
The silver platters are prone to destroy themselves with age if you
don't know the quality of them.

Only time will tell you the true quality of the platters so the only way
to ensure that the data is reliable is to make new copies of them within
their life expectancy. What that is, is unknown ;o)
