Maybe Optane was just a few years too early. There's finally a demand for a middle ground between RAM and SSD.

I’d be okay with only 1.6 TB/s bandwidth in my affordable 512GB GPU. Gotta start somewhere.

You will literally have to have a specific HBF controller on the GPU which I doubt would be any smaller than current state of the art SSD controller.

I am not entirely sure it is a Win Win situation.

I was expecting memristors, fast as RAM and persistent. They used to make strong headlines before the GenAI age.

The technology, called high-bandwidth flash (HBF), is being developed by Sandisk and SK Hynix and aims to provide SSD-like capacities at HBM-like speeds.

Persistent storage in a video card? As soon as advertisers can write to this I would expect "bad things to happen"(c). Will the end users have the ability to access and clean this storage like a regular disk prior to any corporations being able to write into it?

Presumably, yes. It essentially boils down to a high capacity flash drive that is just used to store weights with a fast path to the GPU. It's interesting because I had this same idea last week and had been doing some tests and then this Register article rolls around and it is pretty much in the pipeline. Oh well, one day I'll have an original idea.

Story of my life. One day something novel will fall out of the ether and not decay rapidly.

Keep trying :) Rooting for you. Though with the current pace of innovation in this particular field it is really a tough time.
