A solid state storage device includes an interface system configured to communicate with an external host system over an aggregated multi-channel interface to receive data for storage by the solid state storage device. One method embodiment, among others, includes receiving an excitation signal at a switch associated with a radio frequency identification tag and a disabling material, and changing a state of the RFID tag with the switch based on proximity of the disabling material to the RFID tag. In system, the input device is a transducer.
