I am a total layman w.r.t Hard Drives, but it seems pretty simple (please correct me if I'm wrong):
- They used a technology that impacts performance, that allows them to make higher capacity drives for cheaper.
- The technology used prohibits them from being used in certain application context (citation needed/general consensus?)
- They marketed the product as being suitable for those certain application contexts, when they aren't.
- They come out with a blog, telling consumers to buy their more expensive drives instead?
