> Why do you think the price of SSDs should be close to cost?
Not close, but closeER and at least some evidence of tracking. That's what I'd expect if they were ubiquitous.
Some goods track commodity prices closely. Shrinkflation happens when you can't easily alter the unit price, chocolate bars are a good example. Not that we pay anything like as little as the producers get: there's enough competition that putting valhrona to one side, chocolate prices reflect commodity prices. Same with fuel. Same with ROHC compliant resistors. SMD components. PCBs. Batteries, led light bulbs. DDR memory.
Not SSD. There is no reason it must, this isn't the laws of physics. I just observe it doesn't. If there was more visible competition in supply of inputs, they MIGHT. But it looks like at best a duopoly or tri-opoly of inputs, and prices reflect demand a lot more. Supply isn't even close to demand, there's no surplus.
Those other things are somewhat peripheral. Not saying they don't have a role, but I don't think it's fundamental. I bought 6 "patriot" P210 and they get average to poor reviews for speed and reliability.
