why are SSDs still so expensive? [closed]

Question

I've kind of expected for SSDs to enter mainstream and dominate server storage market by now. But quite a few years have passed and they are still rather expensive (and not that reliable). Why doesn't Moore's law apply to SSD? Why haven't they yet became commodity hardware? Are there technical reasons?

Answer 1

Things cost either a) what people are prepared to pay for them, b) what they cost to make plus the lowest possible margin or c) lower than cost as the seller is using it as a 'loss leader' to stimulate margin-making business down the line.

This is a strong case of a) - the market has not plateaud yet so manufacturers, distributors and retailers are making margin while they can.

Certainly the cost per GB is dropping but there's still a lot of margin to be made. There's still something of a technical battle going on to increase yield per mm and performance but that'll level off in 3-5 years.
