anyone have anything similar to this for safeguarding data backup?

seems pretty cool but if u ever dropped it you would lose 2 drives instantly probably;)
for me a backup needs to be physically in a different location.. to really be a backup
but nevertheless... im hoping to find something like this but as an empty enclosure
