[MaximumPC] Researchers Use Table Salt To Increase Hard Drive Density Six-Fold

post #1 of 39

Think the 4TB hard drives hitting the market now are impressive? You’re right. But one group of researchers say that’s nothing compared to the storage capacities that could be unlocked using a new technique they’ve discovered. Dr Joel Yang and his team from the Institute of Materials Research and Engineering in Singapore claim that simply by adding table salt to an existing lithographic process, they have come up with a way of increasing the information density of HDDs six-fold. Basically, 6TB of info could fit onto today's 1TB platters.

Yang and his team use “an extremely high-resolution e-beam lithography process that produces super fine nano-sized structures†to create the high-density disks, the Institute’s press release (PDF) says. The addition of sodium chloride to an existing, unnamed lithographic solution lets the crew “produce highly defined nanostructures down to 4.5 nm half pitch†– without an equipment upgrade.

That precision allows the team to arrange the nanoscopic magnetic grains on the disks in a tightly-packed pattern, as opposed to the random splattering of grains found on standard HDDs. Whereas standard HDDs have an information density of around 0.5 terabits/sq. in., Yang’s refined process has created disks with densities up to 3.3 terabits/sq. in. However, the number is a bit deceiving; while 3.3 terabit/sq. in. disks have been fabricated, the crew has “only†demonstrated data-storage capabilities in disks with 1.9 terabits/sq. in.

Pretty impressive.

Home servers on one HDD would be nice to see, or truly huge servers filled with these babies (a 75 TB server... bet you couldn't fill that up in the foreseable future).

Sweet, can wait for HDDs with 300MB/s read write speeds because copying 2TB of data to a new drive takes forever...

In before someone actually pours table salt onto their hard drive thinking that it will increase the memory of it. Now Morton is going to have a label saying "Contains iodine, a necessary nutrient, also makes hard drives more dense allowing them to have more memory".

The same thing as we would never need for then 512kb ram. There is always room for more. A home server I know of has 30TB nearly full. I'm sure they had the room for HDD's and more things it would easily fill to 75TB. Never underestimate the need for more.
