Yes, PATA drives are IDE interface.

There's also another wrinkle, which is that anything you plug into the empeg has to have a LAPTOP IDE interface. Just "IDE" isn't enough, because a desktop IDE plugs are too big to fit an empeg.

Edit: The one you linked didn't specifically say it had a laptop-sized IDE plug, but it was very clear that it was a "2.5 inch drive" meaning it will likely have a laptop-sized IDE plug.
