'Millipede' Prototype Shown at CeBIT
neutron_p writes "It was a subject of much controversy for last 5 - 7 years, but it's finally got protyped. At CeBIT, IBM for the first time shows the prototype of "Millipede" - nanomechanical data storage device. Using revolutionary nanotechnology, scientists at the IBM Zurich R&D Lab, Switzerland, have made it to the millionths of a millimeter range, achieving data storage densities of more than one terabit per square inch, equivalent to storing the content of 25 DVDs on an area the size of a postage stamp. The principle of operation is comparable with the old punch cards, but now with structural dimensions in the nanometer scale and the ability to erase data and rewrite the medium."
Like when you drop a three foot tall stack of them in the computer lab and have to spend several hours putting them back in order?
(true story)
...the worlds smallest keypunch.
Oh, no! You have walked into the slavering fangs of a lurking grue!
"The principle of operation is comparable with the old punch cards"
So now we feed these stamp sized cards intot he big machine, and it says "working!, working!, working!" till it spits out another stamp with the answer.
Awesome.
There's nothing Intelligent about Intelligent Design.
This kind of device would be incredible for backup purposes, and the recording method seems to be fast as well, but would they accept almost-unlimited rewrites? In that case, this technology could finally replace magnetic devices. Solid state is always better, but so far, the existing alternatives don't offer the durability and flexibility of hard disks.
That is some insane data density, to have more than one terabit per inch. And here those crazy people though nano-tech would bring about "grey goo" -- little did they know the only goo it'd bring about is from the toughts of Slashdotters having a multiple TB's of porn on myeir harddrives.
Windows has detected an undetectable error.
Unfortunately, I hear that any hardware that uses the "millipede" ends up being a bit "buggy"...
Obviously, on 10 centipedes, rotated weekly.

1. What's the read/write speed?
2. What's the operating temperature requirements?
3. What's the max operating heat output per unit?
4. How many concurrant inputs/outputs can we get into a unit?
5. What's the failure rate/expected operating lifespan?
6. What's the near-term expected commodity cost of these units?
7. Given 1-6, how many units would be needed to make a properly redundant filesystem with at least the reliability and speed of current file storage devices on the market? What would be the expected near-term cost?

For those interested, here are some advantages I see to this technology:
1. Increased storage density. More importantly, this prototype is not near any fundamental limit. Hence, it would appear that there is plenty of room to reduce the dimensions of the MEMS tips to increase storage densities way past what a magnetic drive can do.
2. Data transfer rate. In principle, the thousdands of different tips can all return data at the same time, compared to, say, 4 bits returned at once from a 4-platter HDD. Of course, in real situations, not all 4000 bits will necessarily be of interest, but I think with smart caching and device layout the throughput should be very high (i.e.: contiguous bits in a file are spread out so that the entire file is read by the 4000 tips without anything moving).
3. Low seek times. In a HDD, the head must move by many centimeters in order to seek randomly. In Millipede, the entire surface moves by, at most, 100 micrometers to find a new location. It probably uses piezoelectrics, which are fast and robust. Thus, I see seek times being lower (at least in a mature device).
4. Scalable. This prototype has a single array of tips on a single polymer layer. Obviously it is straightforward to build real devices using 10 or 20 of these arrays stacked. Unlike the platters in a HDD, these arrays could be seeking independantly, so if properly designed, performance could be very good (like RAID maybe?).
5. Heat. The piezos shouldn't heat up too much, and even though the tips themselves use pinpoint heating to deform the polymer, I think the bulk device heat would be lower than a HDD spinning at 10k rpm. Less noise too.
6. Cost. By using established MEMS technology (i.e.: the same lithography used to make microchips nowadays) I don't think implementation costs (and future scaling) will be too expensive (as compared to some more far-fetched nanotech ideas).
This has been in the works for a long time, but I think we may actually see real devices soon! (6 years?) I think this technology has real potential, and I think IBM is right to pursue it.
Millipede was a Centipede clone. With bugs.

What the hell does that mean? I know a postage stamp, but I would rather know REAL standards. What is the LoC/FF for that item? We need to use real scientific standards people. In data storage we talk about bits and bytes, when you talk data density, you can only use LoC/FF. Anything else is ludicrous! It's like talking about car speeds at Furlongs per Week.
Geez. I wish journalistic integrity was a bit higher. It just irks me to-
What? What's LoC/FF?

..was that this news is about 23 years old, and that's gotta be some kind of record. Even for Slashdot.
Weaselmancer
rediculous.
The article quotes 10,000 read/write cycles. Given that this number is probably a slight exagerration for PR purposes, it's a good start, but needs optimizing. Hopefully by the time this technology makes it to market, that will have increased that number enough that it will be competitive with magnetic drives. I think that this will definately be a viable replacement for flash drives.
The technology uses localized heating of a polymer past its glass transition. There is no reason that this should cause much material degredation if it is done properly (i.e.: avoiding temperature spikes, and engineering polymers that have an accessibly low glass-transition temperature while also being robust against thermal cycling). I think with enough engineering this could be done. There is alot of research on heating polymers past the glass-transition temperature, so they won't be reinventing the wheel or anything.
Holding enormous amounts of data becomes less and less useful in practical situations if you can't access a decent sized chunk of it quickly.
But how will we make a backup of those?
Just press it into a peice of silly putty to mirror the surface.

It's one terabit, not terabyte, so closer to 100Gb. Which is 25 DVDs.
A centipede can hold 10 millipedes, not the other way around! Sheesh...

We're getting there, but we're not there yet. And we won't be until storage is truly ubiquitous. I've actually spent some of my weekend re-organizing my music collection, ripping CDs that hadn't listened in a while, etc. But even with the 600G of storage in my PC, I still can't have everything I want unless it's compressed. And I'm thinking about how to listen to my collection in my car. Bringing hundreds of CDs around with me isn't practical. MP3 CDs hold maybe 10-20 albums. HDD based devices (ipods and the like) still can't hold everything I own... not even close. And I want to have a DVD server so rather than pulling out the DVD, I can just call up one of the hundreds of DVDs I own on a menu.
Yes, storage is becoming more impressive all the time. But it's still a very long way from being to the point where you don't have to think about how and where you store and move your files. And it will be very cool when that day comes.

I'm sorry, I'm still confused.
Is that the old VW Beetle, or the new one?
If you don't know what AltaVista is (was), get off my lawn.
I'm really glad that there are still American companies around that are doing fundamental technological research that will improve our lives in the future. Sure IBM may be huge and somewhat evil in it's own way, but at least they know how to actually invent useful things, rather relying on lawsuits and dubious claims of "intellectual property" and whatnot to extract wealth from others.
Unless they're selling two dimensional VW Beetles where you live, this might help you pass your next physics test: The SI unit for volume is the cubic metre. But that's probably not the kind of help you had in mind...
We're all going to be out of work in a few years if this continues! /sarcasm I really like advances like this because it saves us time. Imagine what politics would look like if all of the IT brains that are writing redundant perl scrips suddenly applied their brains to history and politics. It'd probably change the world.
It's just like the industrial age, we can put down our sledge hammers(mice) and redirect our energy to more important things.

Modern magnetic HDD stores on the order of 100 Gb in a 3.5 inch platter, which is ~0.4 Gb/cm^2.
If each surface atom on a material encodes one bit of data, then your storage density depends on the density of your material. For example, let's say that the atoms are on a square grid, and are spaced by 0.15 nm (i.e.: 1.5E-10 m, the length of a typical carbon-carbon bond). That means that you have about 4E15 atoms per cm^2. So if each atom one holds a bit, that means about 600,000 Gb/cm^2.
Of course, actually using each atom to store a single bit may or may not be feasible. On the other hand, using the entire volume of a material (which you seem to think won't happen) may be possible. Various (far-fetched) nanotech proposals exist. Assuming we're allowed to use the entire volume of the material, and conservatively estimating that it requires ~6 atoms to store a single bit, Drexler calculates you should be able to get ~5 bits/nm^3, or 5E21 bits/cm^3 (refer to Drexler, Nanosystems, p. 366).
This is all quite far off. It will require alot of work for us to get anywhere near these values. But in terms of fundamental limits, we have quite a way to go!
It seems to me that this kind of technology has been IBM's wild card for a long time. I think they've got a very good idea of what the face of the computer world will look like in a couple years, and they're doing everything they can to come out ahead. First they become a linux house, most likely because linux has proved to be a very nice archetecture to do things like clustering. Now they're finally using the nanotechnology they've been working on for years in such a way that they've created an amazing new technology like this. A technology, I might add, that has the potential to completely dominate the market and completely change the face of the computer world to the point where IBM is the largest hardware manufacturer in the world.....yet again. I'd love to see what's in their business plan for the next few years.
Total device: 6.4 mm length, tip pitch 100 um
/sec
-> 64 rows and 64 columns
-> 4096 tips
Writing speed (from TFwebsite): 'a few microsecond' (say 10)
-> 4096/10e-6 = 410 Mbit
Per tip: range 100 um, bit pitch 10 nm
-> 10000 x 10000 bits = 100 Mbit
Position resolution (really neat device using micro-heaters): 2 nm over 120 um ->
-> 60000 positions observable (probably 16 bit)

The question behind the questions is what potential roles that this product could fill.
If it can't run at room temperature conveniently, but can be made cheap per storage space and is reliable, then it may be useful in stationary servers for extreme-mass remote storage.
If it can run at room temperature and is somewhat affordable, but slow, it can be used as common backup.
If it can end up close but superior to hard disk in all aspects, then it may replace them.
If it can be fast enough to be used as live memory at room temperature, with conventional memory as cache, then even with a few limitations, it could transform the nature of computers as we experience them.
There's many, many other possibilities. Yes, of course, as you suggest, price will match the market - but the role this technology can play is limited more by it's logical capability than the market. If the possibility is open, it's usually much more of an opportunity if you can create a new technology in a market than to just replace another. That's why my questions are obvious - we all wonder how far this first generation of nanotechnology will take us.

Actually, not too far off the bat... :)
Nanoimprint lithography has been demonstrated to reliably produce replicas in curable polymers on the order of around 10 nanometers.
Basically, you start with a "hard" patterned surface (e.g. SiO2, quartz) press it into a polymer (e.g. PDMS-polydimethyl silizane), heat it up to the glass transition temperature of the polymer (so that it flows and conforms around the master) and then proceed to cool and/or cure the polymer. You're left with a rubbery mold that can be subsequently used to "cast" replicas of the original.
He's not joking, he's expressing disgust with the media's continuous habit of dumbing down units of measurement to the point where they're meaningless. It's irritating to those who actually know what a square millimeter and a bit are.
If a job's not worth doing, it's not worth doing right.
Will it have a hanging chad problem?
You've calulated the volume of the chip
;-)
correctly (apart from using units of mm^2
instead of mm^3), but how in hell did you
come up with the volume of a VW?
1m = 1000mm
=> 7,710,952.32 mm^3 = 0.00771 m^3
=~ a 20x20x20 cm cube

Life is not for the lazy.
Not to take away from the extreme coolness of this, since it is cool, but it's not nanotechnology. It's built using microelectronic fabrication techniques. We're a long way from nanofabrication yet.
It seems, from all I've read about this millipede technology, that the real bugaboo is re-writing bits. I'm wondering just how important that really is. While I would preserve the ability to destroy data (easily implemented by writing pits at every location) I think that 99% of the uses of this massive storage could be done without re-writing.
Let me think of a couple of scenarios for these chips:
1) Music storage and playback, as in an Ipod.
This is a perfect example of something that you never need erase. You very rarely want to replace the previous version of a song with a newer one -- mostly you just want to add to your collection. In the very odd case that I never want to hear a song ever again, I could destroy it.
2) My own business -- visual effects.
We scan and create a few terabytes a year of images. Perhaps surprisingly, we throw almost none of them away during production, keeping old versions of images as reference. Disks are cheap enough that there's no need to erase frames during a project, and these millipede devices promise to be rugged and permanent enough to act as their own long-term backup. We'd just disconnect the drives and store them on a shelf forever.
Clearly, we'd want to change the way that filesystems work -- maybe the directory structure would be kept in flash memory where just the data bytes are on the millipede surface until it's time to inter the disk in the archive.
I think that IBM, and others, should really consider the possibility of non-rewritable millipedes, especially because abandoning that capacity would appear to make everything else much much simpler and cheaper. They might make it into production sooner too.
