Table salt can increase hard drive storage space by 6 times
Thread Content
According to a report in the UK’s Daily Telegraph on October 16, the amount of data generated by companies and individuals, as well as the data that needs to be stored, is increasing day by day. Existing hard drive manufacturing technologies will soon reach their limits, so scientists need to find new solutions. Now, Singaporean scientists are using the seemingly ordinary salt to solve this problem by increasing hard drive storage capacity. Scientists from Singapore’s national research institutions – the Agency for Science, Technology and Research, the National University of Singapore, and the Institute of Data Storage – collaborated to make this discovery. They stated that the new hard drive manufacturing process, by using simple sodium chloride (table salt), can increase the data storage density of hard drives to 3.3 TB/inch, which is six times the current storage density. Joel Yang, the leader of this research, explained that adding table salt during the manufacturing process means that the arrangement of bits (the units of information) on the surface of each disk becomes more uniform and orderly, allowing that surface to hold more bits. Additionally, salt also increases the clarity of the electron beam used to \"imprint\" bits. Joel Young said, “Salt provides high contrast for the electron beam; now we can see fine lines that would otherwise be very blurry.” ” Joel Yang pointed out that if table salt is not used, every effort must be made to keep these bits tightly combined together, but they are likely to end up as a large and blurred mass. The latest manufacturing process will begin commercial production in 2016.

Fresh vegetables contain a lot of water; when pickled with a large amount of salt, the water is removed and the vegetables shrink in size, but they remain the same vegetables. In this way, more vegetables can be stored in the pickling jar, and they are less likely to go bad. Do the same to the hard drive as well – that is, squeeze out the spaces between those 0s and 1s, so that more 0s and 1s can be stored on the disk surface. I’ll try putting my external hard drive in a pickle jar again. How many pounds of salt are needed for 1 hard drive? There are no specific figures in your method. Is that Yang Joel of Korean descent? It should be; otherwise, there would be no inspiration. I still need to thank the original poster for providing such important information.
I soaked the hard drive in 99% saltwater for an hour, and now it doesn’t work anymore. Is it a concentration issue or a time issue? I have a question. Note: This is the company’s computer; it contains important data. MY GOD!

Therefore, there are two possible approaches: 1. Monitor the salt concentration in real time, and use that information to control an automatic dosing system that adds more salt to keep the concentration within a very narrow range of variation； 2. Extend the soaking time; calculate the required amount of salt, and once it is confirmed that this amount is sufficient, extend the soaking time by using the concentration-time curve. It is certain that even at a saltwater concentration of 1%, after being immersed continuously for 876,001 hours, the hard drive can theoretically reach 5.99 times its original storage capacity. Finally, good luck!
Joel Yang is Korean himself, and it is said that salt was invented by the Koreans~ What great creativity!
I’m truly honored that so many people have shared my post on the management page
It’s really a shame that the Koreans invented table salt; otherwise we would have to live like Li Kui, with our mouths tasting completely bland every day. Why didn’t the Koreans invent feces? If they had, maybe everyone would have been pixies before they invented it.
