Graphene overcoats reduce resistance, lowers corrosion, minimizes wear of HDD platters.

There are certainly merits to use graphene here, but in doing so, it will drive prices up. Graphene is not cheap to begin with.

In 10 years it might be a lot cheaper, plus as far as I understand the coating does not require one uninterrupted lattice(which is very hard to achieve now), the coating could probably work with bits of graphene(which is comparatively cheap now).

"drives with a 100TB capacity in about a decade from now"...
In 10 years 100TB will be obsolet, now we have 20 TB.

... they will have to handle extreme temperatures for long durations.

Heat dissipation might be a problem. I didn't see it mentioned anywhere. I wonder how they will deal with cooling.

The cost of graphene depends on the size, uniformity and purity of flakes you need.

Graphene is the main component in pencil leads (you write/draw when the lead sheds graphene flecks that wedge themselves between paper fibers) and one pencil probably contains more graphene than necessary to manufacture one HDD.

Unless HDDs have strict Goldilocks graphene requirements, graphene shouldn't be a major cost driver. The process to give platters a uniform coating and get it to stick could be a different story.

COCs are not optimal for HAMR drives

Don't HAMR your COC. Got it.

Why keep on developing hdd's?? SSD is here to stay! HDD is filled with <Mod Edit> moving parts. DROP IT!!

All my house systems are SSD only.

However...the 65TB in or attached to my NAS...I could either replace that with all solid state, or buy another car.

HDDs have their place.
