100TB hard drives could be possible thanks to graphene
Hard drives aren't intelligent to abandon the ghost just yet, and the latest search promises to get them back along track to hit 100TB capacities in the next decade.
This capacity was initially promised by Heat Assisted Magnetic Recording technology, or HAMR for low-set, but it's hit a a couple of speed bumps on the way. Worry not though, because the wonder material that is graphene has jumped to the rescue yet again to make for a smoother tomorrow for all.
Heat Aided Magnetic Recording technology is still key to hitting huge capacity hard drives, simply as the data density has increased, so the impact of friction, wear, corrosion and thermic stability have stepped in to botch up everyone's party.
At the moment HAMR hard drives habituate carbon-based overcoats (COCs) to protect the drive platter surfaces. The job is, this COC layer is still relatively thick, and that's been limiting the pursuit of high information densities.
Researchers from the University of Cambridge, specifically the Cambridge Graphene Centre, believe they have the answer—replace those carbon paper overcoats with graphene overcoats (GOCs, I guess).
They proven this tabu by replacing carbon overcoats with graphene ones and sure enough, the graphene overcoats lowered grade-constructed detrition, offered improved corrosion protection, and made for much smoother surfaces As symptomless.
If you know your way around a science paper then you can check out the whys and wherefores in this write-functioning over at Nature Communications, but be warned it ISN't especially loose reading.
The takeout Here though is that serious drives still have a place in our PCs, despite the advances made with SSDs. We thrill to think how much a 100TB M.2 drive would cost.
Alan has been committal to writing close to PC technical school since ahead 3D graphics cards existed, and still vividly recalls having to fight with MS-DOS honorable to get games to charge. He fondly remembers the killer jazz group of a Matrox Millenium and 3dfx Voodoo, and seeing Lara Croft in 3D for the first time. He's very glad hardware has advanced as much as it has though, and is peculiarly happy when putting the latest M.2 NVMe SSDs, AMD processors, and laptops through their paces. He has a long-lasting Magic: The Gathering compulsion merely limits this to MTG Arena these years.
