Nanotech To Replace Disk Drives Within Ten Years? 127

Posted by Zonk from the along-with-my-hip dept.
Ian Lamont writes "An Arizona State University researcher named Michael Kozicki claims that nanotechnology will replace disk drives in ten years. The article mentions three approaches: Nanowires (which replace electrons/capacitors), multiple memory layers on silicon (instead of a single layer), and a method that stores multiple pieces of information in the same space: 'Traditionally, each cell holds one bit of information. However, instead of storing simply a 0 or a 1, that cell could hold a 00 or a 01. Kozicki said the ability to double capacity that way — without increasing the number of cells — has already been proven. Now researchers are working to see how many pieces of data can be held by a single cell.'"

      Hard disks are absolutely, with no qualification, nanotechnology. In fact, hard disks were the *first* nanotechnology we ever used, anywhere. Each bit on a modern hard disk is literally nanometers on a side, the read head is a thin film nanometers in thickness, flying above the disk less than a micron above the surface! Saying that nanotechnology will replace that is like saying that wheat will replace rye as the best sandwich containing substance. Moronic.

      When I was helping with a proposal to the EPA for regulating the environmental effects of nanotech, I needed to come up with a definition for nanotechnology. The *only* definition that exists for nanotechnology is a system where the relevant controlled length-scale is less than 100nm. Hard drives are the most advanced nanotechnology on earth!

If the read logic can differentiate 4 levels, then you get 2 bits per cell. You can't go too far this way, as the number of bits you can store is proportional to the log (base 2) of the number of values you can read - noise, drift, and leakage become problems. This stuff is well known in the device community.

MLC typically performs more slowly than single-level cell for two reasons: the amplifier attached to each bit line takes longer to settle to a specific value, and the error correction takes longer to process.

                • >Nonetheless, you seem to take offense at the term "disk" but not "drive", despite both of them being technically incorrect terms, both deriving from elements of motor driven rotational magnetic storage.

                  The meanings of the original terms are not in question.

                  Could you call it a "drive", since its primary storage medium is being driven by SOMEthing? Sure ya could, as I pointed out in earlier posts. That's what the big boys call it in all their literature.

                  Can you call it a "disk"? Well, no, and therein lies my problem. There's no disk to store data to.

                    So... you're doing a "close enough" yourself on that one. At least you're admitting it's a fudge now. I'd love to see you explain to an end user where the "drive" part of the flash memory is, given it derives from the motor. Easy with a hard disk drive. Not so easy when the reason for calling it a drive is simply a holdover from disk drive nomenclature.

  • The major issue of even these new technologies is their fragility:
    their sensitivity to emp and moisture, their tendency toward bit rot, their propensity toward obsolescence, all placing in danger our records as individuals, society, and as a species. (think the original voyager data, the format has been lost iirc)

    We have known about holographic crystal storage for decades now.
    It's extremely high capacity and high throughput.
    Best of all it's waterproof, immune to EMP, not subject to bit rot.

    Hard drives are based on nanotech - They have features on the nanoscale.

    What the submitter may mean is that magnetic storage might be supplanted by storage based on other state variables than magnetic domain orientation, or that non-binary storage (4-bit, etc.) may eventually supplant binary storage.

    Duh.

    Numerous entities are pursuing solid state storage (no moving parts), and have been for years. Flash, NAND, FeRAM, MI transition layers, phase change storage, and on and on...

    But the fact is that currently, hard drives are the most cost-efficient mode of permanent data storage in most applications. In some cases, solid state is more advantageous. As those technologies are developed, one or more will eventually replace hard drives.

    It will be solid state. It may or may not be binary. But it will be nanotech, just like hard drives.

    No. Someday, I will mostly store software on my equivalent of an iPod, media will be stored by Google (who everyone hates by then, since microsoft has become insignificant) in a semi-p2p network based on both servers and users. My download speed will be good enough to stream anything I want.

    Basically, there are two trends I see i personal computing: Computers are becoming smaller and more portable (duh) and internet services are in increasing demand. This means the optimal future computer will be a tiny device with an extremely high speed internet connection. That is the opposite of great amounts of storage. Who needs to have music, movies, photos and TV shows when you can just have good internet access? You still need that if you want the very latest of anything anyway.

      It'll take much more time to have an ubiquitous wireless network with enough bandwith than coming with 'iPod' which have enough capacity to store all your data, so by the time this network happen, people will be used to carry their data with them..
  • Where the fragility and power consumption makes a disk unattractive solid state storage will eat up niche after niche until it reaches parity with the capacity and performance of a disk. Then there will be no more disks. But what is cooler is that there are no 'read heads' that must move in solid state storage. There is no performance penalty for non-sequential access. This is what will radically change the kinds of things people can do, things that are just not possible now.

Flash is looking good, but the mfg capacity is currently no where near what the world would need to replace HDD. The price will be high at first. Hopefully, people will buy these drives.
