SD to SD cable

[Pa Pa Jack]

Please forgive my ignorance, but is it possible to make a cable to connect a digital camera with an SD lot directly to a storage unit which also has an SD slot?

I have a digital helmet camera that will record to a 2G SD card. And I have a 160G storage drive that will accept SD card input directly. I would like to connect them so that I would have, effectively, a 160G SD card to record for long periods of time.

Thank You.
