Are these drives junk?

Interesting question, and while I'm not a computer whiz, I can safely say that no product today has the longevity of products from our past. When is the last time you had a television set that lasted 5, 10, or 15 years. Even the best tvs and electronics of today, don't last more than five years. The industry simply can't survive if you only buy a new one every 10 years.

So, to answer the question, yes, they most likely are junk and probably won't last.
