In the same manner that PDFs are formats that are created so that altering the content and layout of documents would be a difficult task, SanDisk is hoping to take this to the memory card level with the WORM card, which stands for Write-Once Read Many. According to Engadget Mobile, the new SD media card from SanDisk will make it virtually impossible for others to alter the contents of the card, allowing content to only be written once, much like a non-rewritable CD or DVD.
The cards have about 100-year storage life. Not much other information is available. The cards can find use in business documents so that content information cannot be readily changed. It will begin shipping with a paltry 128 MB capacity, with bigger storage options to come. The press release can be found on the SanDisk webpage.
