Flash Memory Won't Get Cheaper Any Time Soon 166

jfruh writes "Some melancholy news from the Hot Chips symposium last week: NAND memory, which powers the solid-state drives that have revolutionized storage, has broken the $1 per gigabyte barrier and isn't getting any cheaper. 'They will always be ten times the cost of a hard drive,' says analyst Jim Handy. There are newer technologies in development, but they won't be able to beat NAND on price for years."

      Actually this is as bad for the third world as well, because what do you think is used in all those ruggedized laptops and tablets in the middle of BF Africa? NAND Flash. The OLPC, smartphones (which is allowing many third world countries access for the first time to the WWW) all of these use NAND flash and as long as flash remains high it will hurt the poor more than those in the first world.

        You say that a high price on flash will hurt development, but when you can fit Wikipedia English into 9GB + 1GB space for the bzreader index file (a good chunk of human knowledge right there), what more do you need?

        You need a maybe 1-2GB more for an OS (not Windows) with office suite, browser, some learning tools, dev platforms, etc. Give yourself and the OS some breathing room, and we're only up to $16 of flash. That's a whole lot less than a fixed disk, and you've still got several GBs free.

        So I still don't see how this is much of a problem. You could push prices below $1/GB, but it would take a huge sea change (drop to $.25 or less) to make a real difference in the price of the device they are installed in. There's already plenty of storage for a reasonable price, if you're willing to forgo luxuries like porn :D

      • Especially when saying something won't happen ever.

        Well, if you look at the article, the prediction is that flash prices won't fall much between now and 2 years from now (2015). Not the sort of prediction that you can really counter by exhuming Sci-Fi writers for quotable quotes.

        • By the way, if you are imagining that Clarke had any realistic notion of what would become possible when, re-read 2001 sometime. It is just as wrong as the old "there is a world market for 5 computers" quote, only in reverse, from cover to cover.
    • When you have an industry where there are a lot of different manufacturers that are not illegally colluding in any way, of course prices are going to avoid dropping. particularly when the first item made costs a million bucks and every one after that costs a fraction of a cent.

      Six months later, you could get one for $399, and by the next Christmas, for $199. So much for that prediction.

Technically a 3570K is 3 generations better then a core 2 duo, but it's barely 2x as fast. Usually you get an almost doubling of performance every generation. The performance gained from i920 to i2500 and to 3570 has been abysmal. Less then 40% increase from i920 to i2500, less then 20% going from i2500 to 3570. That is a huge deal.

    What the article actually says in the last paragraph is that there's currently a capacity shortage, that's expected to be resolved by 2015. The article also says manufacturers think they can go down another process node, and then do another 3 after that using 3D stacking. Then he says new technologies "with the speed of DRAM and the storage capacity of NAND" might make their way out of the lab next year.

      That notion is off topic. The summary says that NAND "has broken the $1 per gigabyte barrier and isn't getting any cheaper." Since the article says prices will be flat through 2015, the article at least in the short term supports the summary.

      The article actually says "Don't expect SSDs to ever get much cheaper." It suggets there may be two more process shrinks (16nm and unspecified).

      Who the hell needs 4TB in a single SSD? You can buy a multiple of smaller drives which total 4TB for a damn sight less than $29K. I don't think people making the price comparison are worrying about the extreme cases. For 'typical' sized drives of each type SSD is getting near $0.50/GB, and HDD is around $0.05/GB. That's close enough to 10x in my book.

        SSD and HDD arent the same thing and are used for different but overlapping purposes. Comparing them directly is just plain ignorance.

        That's a dumb statement. To an enormous extent, SSDs and HDDs are used for different but overlapping purposes precisely because they have a very significant cost difference. In many cases -- almost certainly most cases -- the cost determines which you get (either directly or indirectly), so comparing the cost makes complete sense.

        • Exactly. If SSDs were as cheap as HDDs I sure wouldn't have any of the latter.
        • The point I was making is that pointing out cost/GB disparity adds nothing to the conversation. We currently use SSDs for one class of use-case and we use HDD for another use-case class. Directly comparing cost per GB, as things are now, is unproductive.

Saying that comparing price per GB doesn't add anything to the conversation is like saying that comparing IOPS doesn't add anything to the conversation. If you remove price comparisons, then there is no reason to think about HDDs at all. The only reason that I have any HDDs today is that SSDs of a similar capacity are not cost effective.

      The spot price for NAND right now [insye.com] is about $5 for 8 GB (64 Gb). So 4 TB of NAND costs $2560. Which is pretty close to 10x the cost of a $200 4 TB hard drive.

      When you buy a 4 TB SSD, you're not paying $29k for the NAND. You're paying for someone to go through the trouble of amassing 4 TB of flash, design an arrangement with controllers which can address that huge amount, and produce it in bulk. Very few people are demanding that much capacity in an SSD, so the cost of that engineering and tooling work gets amortized over fewer customers. About $2.5k for the NAND, about $26.5k for the engineering and tooling.

      With the lower capacity SSDs, those production costs are amortized over much larger volumes, and a much greater fraction of the drive cost is the NAND. A 128 GB Crucial M4 drive contains $80 worth of NAND (actually probably a bit more since there's some overprovisioning to substitute for cells which die early), and sells for $100.
