SanDisk has announced new SD WORM memory cards for uses where data needs to be retained in a format that is unalterable. The SD WORM (write once read many) digital memory card is intended for uses like police investigations, court testimony, electronic voting and other applications where data needs to be protected from alteration or deletion.

SanDisk says that data written to its SD WORM cards is immediately locked with no physical way to alter the data or delete individual files. The cards can be read in any standard SD card slot device. SanDisk also says that the data written to the disc has a 100-year archive life.

"As digital media volume has grown and surpassed traditional analog media such as film and audio cassettes in the consumer market, law enforcement agencies and other professionals are facing rising costs and lack of supply," said Christopher Moore, director of product marketing for OEM memory cards at SanDisk. "SanDisk's new SD WORM cards offer professionals a one-stop solution for capturing and archiving critical data, along with many other benefits of moving from analog to digital."
