Its not an urban myth. Its just that people should not be worried about it as that number of writes is quite large eg. Intel says theirs will last 5years with 20GB of writes per day. Dont know that many people who would come even close to that.
NAND chips on the drives have a limited number of rewrites and that is a fact.
If the chip dies of too many writes, you can still read the data from it.
Then the discussion goes into MLC vs SLC...
In normal usage, people should not be worried about the longetivity of the chips. Most issues are with the controllers.
