Roland Piquepaille writes "This sounds almost too good to be true — at least for some time. Physicists from Boston University have fabricated nanomechanical switches which promise fantastic advances in data storage. Their nanodevices will have densities exceeding by orders of magnitude existing storage devices. They will deliver data at speeds in the megahertz (and possibly gigahertz) range, also exceeding by far the few hundred kilohertz of our current hard drives. And finally, they will only use some femtowatts of power each, leading to hard drives consuming maybe a million times less electricity than existing devices. So, where's the catch? Will we ever see hard drives built with these nanomechanical switches? Honestly, I don't know, but read more for other details and references." Ok, we will let this through with the point that one should check the references. With how fast things are moving this may already be out of date. However it is not unwise to be aware of forward moving efforts that may be taking the high ground.
