Is there a volatile secondary storage device?
“Secondary storage does not lose the data when the device is powered down—it is non-volatile.” – Wikipedia The accuracy of the article about Computer data storage’s section about Secondary Storage Devices is of course not 100% accurate. I believe that some company has manufactured a volatile secondary storage device sometime in history, whether it was an early prototype which proved that the method is inefficient or if it was a project that lacked funding and got shut down.
