HDDs cost more because they consist of technologies understood and implemented in factories for long. Manufacturing of SSDs is different, and it'll take some time for manufacturing companies to get up to speed, at least to overtake the scaled assembly line operations of HDD manufacturing.
My bet is by the end of next year, SDDs will be cheaper than their equally sized HDDs. HDDs are certainly on their way out.
- wmf 11y agoSSDs are just chips on boards, which are manufactured using very mature, very high volume technology and yet they improve at best 2x/year. There is no reason why SSD prices would drop 10x in one year. Hetzler et al. have calculated that the industry would have to spent over $800B to build enough fabs to replace hard disks with SSDs. http://storageconference.us/2013/Papers/2013.Paper.01.pdf http://storageconference.us/2013/Papers/2013.Paper.01.pdf
- mcshicks 11y agoI think the big story here is the number of chips they can stack. From the article you pointed out to they were using 8 stacked dies. "The later capacity is accomplished using 8 stacked and thinned (< 75 um) NAND chips in a 1.2 mm package" The samsung one has 48 layers per the article. So that's a 6x improvement.
