It goes with my “every purchase is a crap-shoot” belief, too. However, if there is Old Product sitting on a warehouse shelf in large quantity, those won’t be retail-able because the Brand has released newer models. “How do we sell old products? Repackage them into something newer and shinier!”
So, they can move them off of their inventory shelves (which can be taxable, simply sitting there) and push them onto retailers’ shelves instead so the manufacturer has cleared off shelf-space, escaped paying taxes AND might sell a few.
It might have nothing to do with Quality per se… but just don’t ask, “Why didn’t they sell as a bare drive in the first place?” ha ha
