IIRC this is RW unlike that “crystal disk” thing a couple months ago which was write-once.
At this stage its a very expensive slow storage medium. Hopefully within a few years they can derive workable tech from this that maybe has less density, but is marketable
and you have to keep it cool , at 196°C …
Storing 1000000 TB in one gram of DNA is what
Microsoft & probably others are researching & racing for …
We will be the nodes! -mind blown-
It requires cryogenic temperatures, because the atoms have to be easily movable by the primitive equipment, which implies that they are attached to the substrate by nothing more than vander waals force. At higher temperatures they would jiggle about so much that they would fly off the surface. Drexler has described in his books how to constrain atoms and molecules so that room-temperature thermal vibration would not prevent them from acting as parts in classical machines (gears, pulleys, pistons, etc). And at that scale, such machine parts would move at speeds comparable to electronic circuits. But it is early days building the tools to build the tools to make such atomically precise mechanisms.
I offer two contrasting examples of this technology below, one here-and-now and one a bit far off but very inspirational.
“Towards a matter compiler”. The title is a bit of an over-statement. It is actually a presentation of work demonstrating a molecular “flip-flop” operated by a scanning-tunnelling-microscope. That’s cool, but as such it is the equivalent of computer technology circa 1940. Now, you might argue that technological progress moves faster today. OK, but even if it moves three times faster, that means we still won’t have the molecular equivalent of the Intel 8080 much before 2030.
“Productive Nanosystems.” A delight to watch.
