SanDisk's SD card can store data for 100 years

SanDisk on Wednesday announced a 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.

The media comes with capacity of only 1GB. SanDisk determined the media's 100-year data-retention lifespan based on internal tests conducted at normal room temperatures.
