Coating HAMR HDD platters with graphene could increase storage capacity by up to 10 times

One of the main components of a HDD is the platter, which is usually covered in carbon-based overcoats (COCs) for protection. Through the continuous development of these layers, their thickness has reduced from 12.5nm to 3nm, resulting in a data density of 1TB per square inch.


By replacing between one and four COCs with graphene layers, researchers found that it's possible to increase data density tenfold. After testing graphene layers' friction, wear, corrosion, thermal stability, and lubricant compatibility, they found that graphene "enables two-fold reduction in friction and provides better corrosion and wear than state-of-the-art solutions" and reduce corrosion by 2.5 times.



Good, I need a 40TB hard drive.

And with the way things have been going, they'll be just as readily available to consumers as high-end GPUs when they debut.


I bought a new 10 TB Seagate BarraCuda Pro for $210 a couple of years ago. It now sells for $300 new. Not that I need it, but I can't upgrade to 12-16 TB right now without paying something stupid.
