I've enjoyed the idea of self-destructing data for awhile now, but it always leads to the possibility of DoS attacks against my own data.
This smartphone app and token, how do they communicate with the drive? Does it use cryptographic signatures to make sure that it's actually my phone talking to the device and not someone else, or just a passcode?
Does the drive send out an alert if it receives more than X SMS messages, where X is configurable? What's to stop someone from sending random texts to it until it self destructs? Simply the that they don't know the phone number?

It depends on the nature of the data you want to store: there is some data which you would be concerned with letting others get access to but whose existence is more important, and other data where you absolutely must not let others get access to, even if it means that no one (including you) can. This drive is designed for the latter case.

How long does the battery last?
