It's almost as if no healthcare legislation gets passed before private insurers have figured out how to extract shareholder value.
(Which makes the system worse. The fiction of a fiduciary responsibility to extract top dollar from a business regardless of consequences is the opposite of "capitalism". Which derives its name from the practice of sound investment to build something of lasting value.
To say nothing of the social deviance of for-profit healthcare.)
I think a read cache device gets set up like RAID0, interleaved reads rather than redundant data.
Examples of auxiliary devices where you want redundancy: there can be a write cache (the ZFS Intent Log, or ZIL). You can also dedicate a fast device for hot items like the deduplication tables, or a dedicated device for tiny files where data can be stored directly in the directory data, rather than allocating a separate data block.
Although the lede suggests that this is about the consequences of healthcare costs in the United States, the research is from Denmark.
Even so:
Denmark has a universal healthcare system, [not] massive healthcare bills that usually ruin people's lives in the United States. Yet, the researchers suggest that economics still plays a big role... Patients who showed the steepest income declines had the strongest links between cancer and crime.
While the original OS X display model, Quartz, evolved from Display PDF via NextStep, I believe that it shifted back to pixel rasterization to offload more of the display stack onto the GPU.
Quartz Extreme?

It's possible that existing consumer video cards could be coerced into doing efficient vector drawing in hardware. Apple tried to do just that in Tiger [note], but then had to back off at the last minute and disable the feature in the shipping version of the OS. It remains disabled to this day.
