I think back to when HDD's were "getting cheaper" at $1/MB (and every power of 10 since at that same price point) and shrug. While they'll certainly still have their place (similar to tape drives and other storage technology that used to be much more commonplace), there's every reason to expect the PPU of SSD's to continue trending downward.

Not really. The big driver for cost reduction in SSDs was process shrinks, but the latest processes are actually more expensive per-transistor than older ones so that ship has more-or-less sailed. You've got 3D NAND but that's even more expensive to manufacture so the cost savings are marginal at best. It remains to be seen if XPoint will lead to big savings.

In the short term SSD prices have actually been trending up due to a shortage of NAND flash.

To my point, this is still the same argument that has been made time and time again with regards to storage. Short term upticks are easy to see in historical SSD pricing, even when looking at the longterm trend.

If you think this is the same you haven't been paying attention to what's happening in the industry. Moore's Law as we know it is dead, shrinking the node size isn't cutting costs like it used to. A lot of people are still in denial over this, but it's going to have major repercussions in the IC industry.
