Special SanDisk SD Cards Adopted by Japan’s Police Force

SanDisk has just announced that Japan’s police force has adopted its 1GB SD WORM memory card for collecting evidence. The Write Once, Read Many cards are tamperproof, can only be written to using a WORM-compatible device, and supposedly stores data reliably for 100 years. Practically speaking, this means that photographs and audio can be collected onto the cards, allowing those who access the data later on to be confident that it wasn’t tampered or edited in any way. The National Police in Japan have tested the technology extensively, and seem to be convinced of SanDisk’s claims.

We can’t really think of any practical application for ordinary photographers (can you?), but it’s interesting to know that this kind of technology is out there and being used.

    Honey, you are so special to me that I'll only capture you with my WORM.

    In terms of practical use for photographers, just think about having the negatives of a film roll, and what you would do with them. You guarantee yourself that you can't delete originals, and based on how you like to shoot you have a nice souvenir for customers. I have been asked plenty of times for all the originals, even if they haven't been retouched, edited, etc. I'd be curious if the “WORM” cards are any cheaper, then it could be an option to give those who started after digital took over, a chance to understand the challenges that came with film. When you have only so many exposures, I personally felt that a lot more work had to be in shot composition, and I was weary of throwing a camera into continuous shooting.

    Maybe as a “secondary media” for cameras, in order to have something like a film roll with the original pictures.

    I can think of one gigantic practical application for this: Archiving

    This sounds like it would be better than archival disc media or HD storage. In my experience, optical media starts to rot in under 5 years even when stored in ideal conditions. (note: I haven't done tests with archival gold discs, but I have little trust in the whole format since optical drives seems to be slowly going the way of the Laserdisk.).

    Hard drives are no better. If they're not spun up every 6 months or so, they can seize. And, it's also a victim of technology progression…motherboard ATA/PATA connectors are almost extinct, and no doubt whatever is in the works to replace SATA will be along soon. (If you've got gigs of pix on ATA drives, better at least transfer them to SATA soon.) Hard drives are also vulnerable to shock, static, and drive board faults.

    These solid state WORM cards seem like the best solution I can imagine as far as long term archiving goes. (Just have to buy a bunch of USB readers and archive them with the cards.)

    Only problem is capacity…it's many times more expensive per GB than other storage media.
    But, that could come down if they're marketed as the archiving solution for all media.
