North Carolina State researchers have made a big breakthrough in data storage tech, and it's all thanks to some very tiny dots. Using nanodots – tiny nanoscale magnets – the team has manufactured chips that can hold an unprecedented amount of information using surprisingly little real estate. Each dot contains a single bit of data; a one square-inch chip can store over one billion pages of information.
The real technological breakthrough is in the nanodots themselves. Not only can the researchers lay millions of flawless, single-crystal dots on a tiny chip, but the dots can be aligned to face the same direction. That uniformity makes the dots readable and writable for anyone who has the proper device to interact with nanodots.
Therein lies the next challenge: The researchers have to now create some kind of magnetic packaging that will allow users to tap into the nano-wealth of information stored on the chips – likely some kind of laser device that can access such a tiny medium.
If they can get it all working smoothly, the NC State team could initiate a huge leap in computer memory-tech; entire libraries worth of information could be stored, bit by bit, on a single chip small enough to fit in a handheld device.
Very cool, but i am wondering how this will stand up against magnetic fields..
We need to develop storage methods that can maintain perfect quality of the data for thousands of years and withstand all forms of damage.
It gets old backing up data from one storage medium to another as they wear out.
Can we get some details here?? How much data is "one billion pages" (I can't help but think Austin Powers here)
Also, exactly how big is "surprisingly little real estate"???
at first i didn't think that would be that much data but it turns out to be like 8.3TB. amazing. although the laser reader thing makes me hesitant to buy a blueray player.

Suggests that about 400 words per page is about average, so about 2400 characters including spaces. Assuming ASCII characters, one billion pages would be about 2.18 TB per square inch. They do say billions, so they seem to suggesting atleast double that.
I believe HDDs are at around 50 GB/sqInch, so this is somewhere around 100x as dense [granted HDDs can do several platters in the same space].

"We need to develop storage methods that can maintain perfect quality of the data for thousands of years and withstand all forms of damage."
That's easy for any data that is truly desirable; that's just peer-to-peer filesharing. Not even a nuclear war could erradicate commodore 64 games, songs, emulators, intricate descriptions of the hardware to a pornographic level of detail. This works for any data where there is a large body of people who want to store, use and share the data.
wowlfie, that's not a given. Harddrives have a higher idle power(you have to spin a disk at over 120 rounds per second even when you're not using it) than flash-based SSDs, but the power used to read or write a given amount of memory is much lower for harddrives.
If you're in a word-processor or browsing the internet or some other light activity the SSD uses less power; but if you're doing something a little more heavy duty, like scanning for viruses, compressing files, copying files or streaming lots of data from file in a demanding game the HDD will use less power to perform the same amount of work.
Some peoples underware remembers more than they do..."Racing Stripes Reveal Coded Alien Text in Large Smelly Array" and we were using Deep Space Network for what?
