The article linked here is overly geeky and most dentists may not bother to check it out..but it just makes my nerdy heart tingle. The basics are that researches are using nano tech to replace traditional mechanical storage (than means a hard drive) with solid state electronic storage that will store more faster and cheaper.
Remember when we were warned that if we used digital record dental software to store charts, photos and x-rays our dental offices would run out of storage capacity. Never going to happen. Already a typical dentist practice can put all his/her office records on a tiny thumb drive and drop in a pocket. Just a few years ago those same records took up an entire room.
Dr Narayan says that the technology could enable you to “store over one billion pages of information in a chip that is one square inch.”
