Protein-Packed Hard Drives Promise High Capacity

Digimax writes "The New Scientist has an interesting article on a technology being developed by NanoMagnetics which involves using a protein responsible for storing iron in the body to store data on a hard drive. Is this the start of the BioTech revolution?"

    It seems to me that if hard drive capacities continue to grow at their current rate, in a few years they will have outstripped the porn industry's ability to fill them.

    Yea, this is all fine and dandy, but doesn't help with speed.

    The real revolution waiting to happen is solid state hard drives that are affordable. Until we get rid of the moving parts, hard drives are going to be very very slow, relatively speaking. For the desktop, this is more important that storage space, since we already have 240gb drives that few can fill.

      More ram incurs more overhead. After a point, it ends up slowing your box down if you are not actually USING the extra ram.

      Even with a 15k scsi drive, if you handle large files, which is becoming more and more common, the hard drive is going to be the bottleneck. Even if you only handle small files, the access time for a hard drive is generally 100 times slower than the access time for ram, regardless of how you RAID it, or the spindle speed. That is a lot of idle time when loading large files, or accessing lots of small files. Granted, SCSI helps because it takes the load off the cpu.

      I can't possibly see how your athlon 2200 is the bottle neck, except when you are doing cpu intensive stuff. If I am pulling a filter in Photoshop, yea. Raytracing, etc. I expect that. But I use photoshop every day, and the amount of time I spend pulling a filter is still much less than loading and saving files.

      Generally things go faster as they get smaller. At the nano-level, I suspect that the the difference between "solid state" and "mechanical" blurs a bit.

      As for the speed thing, different storage types have different merits. A great deal of information is accessed rarely. Look at the newspaper. Today's edition will be read by several hundred thousand people...the service delivering this page needs to be fast.

      The archives of yesterday's news has a different dynamic. The June 7th, 1981 sports section might be accessed once or twice per year. The indexing device for the archived paper still needs to be fast...the data itself needs to be on a slower, reliable media.

      The true art in computer design isn't just having the fastest components, but having the components matched to their tasks.

      >>Just because most people want to upgrade their computers one piece at a time over the span of 5 years doesn't mean that they shouldn't be forced to upgrade all at once every now and again, it helps the economy and overall, helps drive new innovation.

      Does this sound like the line of thinking over in Redmond or what?

      Holy shit. Someone should be forced to upgrade? WTF? Why should that be? Should I be forced to give up my classic 1974 Chevy Impala because it's not 'up to date'?...because there are newer and more efficient engines available? Why is a computer any different?

      I don't mean to attack the author personally, but I don't like this kind of thinking.

    "Aligning individual magnetic grains is a problem for all of us," agrees Mayes.

    That quote struck me as funny. Like he's talking about world hunger or something. He's got a point, though...I do have a real problem getting individual magnetic grains lined up--in fact I can honestly say I've never successfully done it.

    If I come up with something more insightful to say, I'll post it to this afternoon's dupe.

    Is this the start of the BioTech revolution?

    Yup, recombinant protein therapies and artificial livers were cute, but biotech hasn't yielded any _real_ products until someone started making larger capacity hard drives!

    I was about to indignantly jump onto my molecular biologist high horse, and started laughing instead. Can't really criticize -- as far as I'm concerned, all that mysterious stuff physicists do seems impressive but it's nothing to me until I can stop worrying about downloading one SHN file too many.

    I'll paraphrase William Gibson

    "Doesn't it seem weird to have these high-tech computers with little spinning discs inside them. It seems like a hold out of some Victorian technology - like a more modern record player."

    Solid state has to be the way to go - no more waiting for your computer to "boot up", just turn it on and it's running your desktop, right where you left it last. Sure solid state SEEMS expensive now, but remember how much a 40 MEG hard drive cost 15 years ago? We just need to throw money at it and the price will drop. I mean come on chips are CHEAP - they're in everything

  9. New Scientist article sucks by Muhammar · · Score: 5, Insightful

    New Scientisct article writen by somebody ignorant in material science: skips the important stuff and dwells on marginal. The company site more informative.

    Magnetic particles in storage media must be evenly spaced and right size. This protein is used as a mold and spacer for making and placing the magnetic particles. The protein is spherical, has cavity which can be filled with magnetic stuff and forms crystal-ordered-like monolayer on support surface. Burning the protein leaves the magnetic particles in caramelized yuck. All this done in with external magnetic field. And since we are baking it well above Curie temperature of the magnetic material, cooling will produce the particles nicely magneticaly aligned.

  10. New Scientist... by JDevers · · Score: 5, Insightful

    I'm going to point out something that no one else seems to have noticed yet. This is an article in New Scientist, that should be enough said who ever actually read it. The have a real penchant for investigating off the wall oddball ideas then writing up the issue with just enough slant that one who reads it takes the same mentality as those who think cars which run on water have been made but are being held back by the big car manufacturers and oil companies. Virtually every issue of New Scientist has at least ONE grand convoluted conspiracy theory. I'm not saying there is no basis at all for this, just that New Scientist isn't exactly a reputable news source much less something approaching a peer-reviewed scientific journal. They are much more like Scientific American but don't even approach that level of credibility.

    That said, go ahead and debate it all you want. I just think (as a molecular biologist...more DNA focused than applied protein mechanics like this, but still fairly well versed) that by the time all the "bugs" for this are worked out we'll have leapfrogged the whole idea of magnetic media Winchester syle drives. This is the equivalent to making a perfect artificial diamond point for a record player, by the time we had the tech to do it the world had already moved onto CDs or other media for the overwhelming majority of uses of said records...People still make record players, but they are a niche market to say the absolute least.

      The technique is very clever, but it is fringe. This is a very small company developing new technology. They may win big, but right now they do not have anything marketable and won't have too soon. They operate on private financing and have to advertise their cutting-edge proprietary technology breakthrough whatever to attract investment to keep going.

      I worked for a company like this, so I take it with some scepticism.
