SecureDrives GSM-Equipped SSD Will Physically Self-Destruct With a Simple Text Message
The drives have a SIM card embedded onto them, and the worldwide roaming capabilities mean that the right text message to the right number will render the drive useless and impossible to salvage. There's a physical destruction mechanism onboard, so you best be sure that you really want things gone forever before sending the text.
Beyond that, the drives also have a few other tricks: if someone tries to pry open the case, the self-destruct code will go off as well. There's no word on pricing, but if you're the type who can't ever be too careful, does the MSRP really concern you?
