I totally agree with you. For this particular article, if there is a clear and comprehensive specification on how the drives should perform (IOPs, latency, BW, etc), the problem will be resolved immediately with no controversy. The comment I was replying to implied that Apple should provide a means for customers to distinguish the products, which I do not believe is a realistic solution because swapping components is quite common in hardware world.
I agree with you too! I'm just expanding on that a bit, and saying how even if distinguishing the products was somehow realistic, it's solving the wrong problem anyway.
