The drive (which can be used in a computer and externally via USB) comes with a yearly GSM subscription, allowing you to send a text to kill the drive. The drive can tell you if it was moved; it can also tell you how many times the password was tried, and if it goes out of GSM range.
It can destruct automatically based on those criteria as well—if you don't want to pull the trigger and send the text yourself. We're hoping the next drive takes a sunglasses form.
