Researchers using salt to increase hard drive capacity

  1. Researchers in Singapore have discovered a way to increase hard drive capacity by as much as six times the current limit using sodium chloride, otherwise known as table salt. Joel…

    Aha, just what I always wanted. Now if I ever get lost on a remote island in the middle of the ocean, I can eat hard drives for sustenance!

    On a more serious note, I was thinking of buying an external hard drive just for emergencies, but I think I'll hold out a bit longer and see where this goes.

    It makes you wonder if you'd lick a platter if it would taste salty.

    So for future notice when your system crashes grab your hard drive with your right hand and throw it over your left shoulder.

    Of course this is relevant! When they get a 1tb SSD that is sub$200 hell to HDD.

    So far and for many (At least more than a couple) years to come HDD are here to stay.

    Think about this though, wouldn't you like to have an 18tb hdd for less than $200? That's a hell of a lot a data even in today's world. Someone could probably come up with an internal raid-like architechture that allows data to be put on each disk four times (or any given number) for faster search speeds because it would be able to find any one of the four instead of having to find a certain place.

    Now even our hardware will contain salt!
  8. If you get stuck on an island in the middle of an ocean the last thing you will want will be salt!

    What about silicon?
  10. It is certainly relevant, because as you increase the density of the data you increase the speed of the hard drive.

    If you clump 2 TB of data per square inch rather than .5 TB per square inch, the hard drive needle wouldn't have to move around as much to reach the data you are trying to access.

    That could potentially make hard drives employing that kind of density faster than current flash drives.

    what happens if water condenses on the hdd when u shut it down?
  14. ocean already contains lots of salt lol
  15. You know, instead of trying to really increase hard drive capacity, because who is going to really need multi TBs of storage but if you do need all that, get another HD or an external one,( one big HD would be hard to back up and it would really be bad if it went out, I would rather have a bunch of drives than one BIG one) but I would really like to see is more ways to increase memory. Imagine a couple TB of RAM!!!

    I think the point here is that the money:memory ratio may increase.
  17. I think the point is that hard drives can be made smaller...

    I'm curious about data durability as these things go forward. What then becomes the life expectancy for these drives with these new materials?
  19. there will always be a demand for HDD storage and this cant be fulfilled by flash drives. Today we r living with 1080p videos which consume TB and TB's of storage space. Tomorrow there will be 4k and 8k videos each video consuming TB of data to store. What will do that time? NO doubt that we will and will always require higher capacity storage device around us to fullfil those demands. I am gonna buy many more HDD for this. No one will buy more than 1flash drive for use but ppl will and alwyas buy more than one HDD for storage.
