Memory Card for One Writing Only?

August 24, 2007

In the recent Q & A of the technology section from New York Times, regarding “How long can I store pictures on a memory card?“, the reply mentioned the follwing:

This year, a representative for SanDisk announced that the company was working on low-cost memory cards to which files could be written only once. The company says the cards, which are still being developed, will be able to store data for longer periods.

A SD-R card maybe? πŸ˜• SanDisk and other similar companies want to get into the market of hard drives, and have rolled out flash hard drives, also called solid state drives. Now SanDisk are thinking to replace the DVD+/-R SL or DL?

Maybe they can make some special copy- and write-protected memory card that will self destroys after one reading. Good for both FBI and big companies. 😈

By the way, the photo files in my old SD card are two or three years old and are still readable. Better than some cheap DVD media. Will the memory card for one writing appeal to the customers? πŸ˜• After 5 or 10 years, even though the data is preserved, you may not have the hardware to retreat them. It’s the same problem as the file formats.

I still have a 16MB SmartMedia Card, about 5 years old, but I wonder who still has a card reader that can read/write it. πŸ™„
