20 years ago there was a fire in a memory plant in Japan and the RAM price skyrocketed like crazy until more companies decided to open plants a little bit all over the world, and we never found again expensive memories, the price kept going down and down because it allowed companies to launch themselves on a market with a strong demand because there was no risk of competition and ROI were high enough. Similarly the situation for pricey hard-drives might come to a near end because the demanding market is going to create opportunities, but it's not going to happen overnight. I read that some people would prefer to buy SSD's instead, but it won't curb down the price in hard-drives. Competition has to be created within the product. One of the reasons comes from the fact that if integrators don't get their hard-drives cheap they won't be able to sell any desktop, we would find ourselves with prices from the 90s.
Also on the market, there are already integrators that change their strategy and stopped selling hard-drives to their customers so that they can focus more on a complete product offer and can honor their maintenance contract with their partners, but there are not very far right now from not fulfilling their contract due to the shortage of hard-drives. It might be very possible that within a few months, we'll see less innovative products on the market if nobody reverses the shortage situation, and i doubt that people will pay an extra $400 to buy a product with an SSD inside with less capacity given the situation of our economic recession.
