Graphene hard drives are stored ten times as much data



Just slap some bad boy on the graphene and see how it works.

Graphene drives

A team of scientists led by the University of Cambridge has developed a new ultra-high-density hard drive that they say has ten times more data storage than other leading devices – thanks to the ultra-thin graphene coating.

Graphene, which is a material made from a layer of carbon one atom thick, is a bit of a glamorous favorite in the science of material sciences to such an extent that it’s almost a meme to incorporate it into almost anything, whether it̵

But in this case, there seems to be a significant difference, according to a study published in the journal Nature Communications, and research in Cambridge could herald a new era of heavy-duty hard drives that make today’s storage problems seem trivial.

There is nothing magical about graphene that makes hard drives suddenly work better. But the ultra-thin material reduces some of the filler that is built into the devices, allowing for greater storage density and performance.

Hard disks are essentially made of fast-rotating plates that are protected by carbon coatings (COCs). As technology improves, manufacturers make these carbon layers thinner and thinner. But there is still room for improvement: replacing COC with even thinner layers of graphene means less bulk and more physical space that can be reallocated for data storage, the press release said. It turns out that graphene still works great as a protective coating, so there are very few trade-offs with the abandonment of COC for graphene.

“Demonstration that graphene can serve as a protective coating for conventional hard drives and that it is able to withstand [data recording] conditions is a very important result, “said Anna Ott, a researcher and co-author of the study at the Cambridge Graphene Center. “This will further encourage the development of new high-capacity hard drives.”
