New Secure Data storage made simple. It only writes the data once, and then locks, so this means no tampering with the data written, and no adding additional information to the USB device. If you are looking to store data without a need to once again write to the drive and secure the information, this is worth looking at, and not that expensive either. Good for storing information under the rules and regulations of HIPAA. BD
THE SD WORM is intended for storing files from police investigations, court testimony, electronic voting, cash registers, security cameras, black box flight recorders and other highly sensitive records. The cards are locked as soon as they are recorded, and can be read in any standard SD drive. 128-megabyte SD WORM cards are currently available, with the capacity expected to increase with time.
