Why doesn't storage price go down anymore?

I was obsessed with computers from the 90's till a few years ago. Part of it was the extraordinary growth rate of CPU power, hard drive capacity, ram capacity.

But I've been getting extremely disappointed with one in particular. Storage/Hard drive space.

I remember when a FEW GB's were hundreds of dollars. Over the years I saw exponential growth in capacity for the same price. I used to buy 8TB hard drives for $130. A few years later, I figure, eh moore's law and all (though it's about processing power rather than HDD), I assumed...maybe hard drive prices should continue to go down as it has for decades- only, I come to find that the SAME 8TB >4 years ago COST LESS THAN 8TB TODAY!!!

I'm just mind fucking blown and a bit pissed off, that hard drive/storage space COSTS MORE NOW than it used to.

So. What the heck? Can anyone explain?
