Let the hive mind of Engadget get that for you.
"We need a digital camera that can be switched on and fire off that first shot fast. It's not a commonly tracked statistic on any review site, and nobody seems to have this information for every camera. We were hoping other readers could inform us as to what small digital cameras can fire off their first pics in under a second (ideally under half a second). It needs to be small, but mostly, just really quick in operation. Thanks!"
I don't know if anyone has opened many hard drives but that is the weirdest read/write arm I've ever seen. The inertia to move that whole arm assembly thing would take a lot more power than it does to move the standard ones.
Also I think they could have kept the platter a little cleaner for a sample picture.
That pic is obviously NOT any type of sample drive using the technology, but instead a relatively ancient drive. I recognize that actuator arm drive as being the type that was in use even before IDE became a standard.
Engadget obviously did not have an image to go along with the article, grabbed a random HD pic, and happened to get one of a rather old drive.
