SanDisk WORM SD Card Can Store Data For 100 Years
CWmike writes "SanDisk has announced a 1GB Secure Digital card that can store data for 100 years, but can be written on only once. The WORM (write once, read many) card is 'tamper-proof' and data cannot be altered or deleted, SanDisk said in a statement. The card is designed for long-time preservation of crucial data like legal documents, medical files and forensic evidence, SanDisk said. SanDisk determined the media's 100-year data-retention lifespan based on internal tests conducted at normal room temperatures. The company said it is shipping the media in volume to the Japanese police force to archive images as an alternative to film. The company is working with a number of consumer electronics companies, including camera vendors, to support the media."
.. then they started to rot at 3-5 years, in my experience..
Post this again in 100 years, until then, it's just more bullshit marketing.
Until you realize that the last reader for it will be extinct in 20.
I'll buy one so I can put it in my time capsule along with my 8" floppy and punch cards.
Extrapolation is a dangerous and deceptive marketing strategy. If it is supposed to last 100 years, they should test it that long.
Nobody is going to sue in 100 years anyway...

So they state 100 years, based on tests at room temperature. Can we assume that the media will always be stored at room temperature in 100 year period? My experience generally shows this is wishful thinking, because air conditioning breaks down, heating fails, the room is not always dark, can have direct sunlight etc. Provide me something that can last a 100 years in conditions of, at least, 30 degree centigrade variation, and then it might be interesting. Certainly I won't be around to appreciate the end results, but for archival this is a requirement, IMHO.
Jumpstart the tartan drive.
Wow, I submitted that like a week ago.
Your submission was undergoing testing for the last week at room temperature and the editors are now confident enough that it will be acceptable.

For non-repudiation purposes, digital data can have a cryptographic hash computed on it. It can also be signed with a timestamp by a trusted third-party. If you're concerned about data being tampered with after it is on the card, the police can simply publish a cryptographic hash of every card they archive after they have written to it. In fact they can do that regardless of how they store the data.
I find it funny that people actually think we won't be able to recreate old technology and we would have to go to museums to get the latest working readers.
Furthermore data will just be copied and copied and copied to the latest hype so these usb cards probably won't still be around by then.
...since the 'other news' today says that's all we have left [ http://www.physorg.com/news196489543.html ]...
Every time I hear one of these "but.. but but nobody will have the technology to READ these things in 100 years!" all I hear is "everyone will be stupid in the future".
Someone recently created a device to read some crazy obscure technology produced by Edison to record sound on film, and that wasn't even all that valuable.
The real deal is, if the data is important enough someone will maintain the technology to read it, or re-create it.

It's not as simple as stating paper. There is good and there is bad paper when it comes to longevity. Papyrus (dead sea scrolls) and lint paper are good, but paper used in newspapers is decaying. The yellowish color that it gets over a few years is an indication of it's decay. It can be stopped, but at a cost.
Even laser printed paper have problems - the printed text is only sticking to the surface of the paper. Ink penetrates the paper more and bleeds into the fibers. But some ink is better than other so the ordinary inkjet ink may not be a good choice anyway. A classic ink based on metal (E.g. iron) may be a choice since even though it may change over time the print will last.
Laser etching in a glass pane would probably be safe from decay but would be hard to store safely - and be expensive. At least it would probably last long enough to allow the world to forget that this civilization did exist.
If builders built buildings the way programmers wrote programs, then the first woodpecker would destroy civilization.

Get an identical card. Copy the data to HDD, tamper away, rewrite to new card.
Tamper proof my arse.
. . . we called them PROMs. If you have an original IBM PC, its BIOS was in PROM. I bet most PROMs still are readable.
Glass would deform in that time scale...
I'm guessing your talking about the urban myth that glass can flow and melt? Sorry, but glass doesn't melt, it would hold it's form as long as it isn't shattered.
Attention... all grammer nazi"s! Is they're anything; wrong with: my post,
