Bits Stored on a Single Molecule Could Lead to Petabyte SSDs

If there ’s one fact of computing life-time , it ’s that there ’s never enough damned repositing , and if you think it ’s unfit now , just expect ’ til you ’re downloading 4 KB flick . Still , research is at least keeping up , and now scientists can store fleck of data on single corpuscle — which could pave the room for petabyte SSDs .

The project , undertake at the Karlsruhe Institute of Technology , saw researchers embed a magnetized iron atom into an organic corpuscle made up of 51 corpuscle . The idea is that the constitutive casing protects the information stash away in the cardinal atom , while its magnetization allows data to be stored .

In fact , by applying current to the molecule , it ’s possible to flip the lonely atom ’s magnetic charge , neuter the underground of the particle . later on measuring its resistance allows the researcher to translate the state of the atom , and then transfer it again and again . That procedure imply the molecule is capable of hive away a bit of data . The result ispublished in Nature Communications .

Typical magnetic drives currently necessitate 3 million atoms per bit so , in hypothesis , a twist made using these new atom number could pack in 50 thousand times as much data in the same size . That ’s the same as own a standard SSD capable of storing PiB of data .

Except , umm , it ’s not quite that prosperous . You ’d have to find some way of addressing each and every molecule in the drive , which is an harebrained estimate . In realness , a equipment would include so much circuitry that — even using nanowires — it would n’t put up quite the mental ability boost that reasoning promises .

The concept , however , could well inspire alike techniques that could be used to shrink current SSD engineering by orders of magnitude . So the petabyte SSD might not be quite as ridiculous as you first thought . [ Nature CommunicationsviaThe Register ]
