rapiddisk
An Advanced Linux RAM Drive and Caching kernel modules. Dynamically allocate RAM as block devices. Use them as stand alone drives or even map them as caching nodes to slower local disk drives. Access those volumes locally or export them across an NVMe Target network. Manage it all from a web API. (by pkoutoupis)

Does QEMU support C++?
I guess I'm really not clear about how QEMU works. There's a QEMU SSD project here called FEMU which emulates a block device. If I wanted to basically have FEMU utilize a C++ compression algorithm instead of a C compression algorithm would there be anything I would have to change about QEMU itself, or can I just change it to use G++.

How do I load RapidDisk --
I found that an alternative on Linux is RapidDisk. I installed it with no issues. However, I have to open terminal and enter a couple of commands manually to re-load the RAM drive as cache after boot, specifically:

PrimoCache equivalent for Linux (Ubuntu)?

Plotting destination file system
As for ramdisk cache, what I was looking into is Primo Ramdisk which was mentioned a LOT around here, especially with high density plotting. Unfortunately that is only for Windows, but I found something similar for Linux: https://github.com/pkoutoupis/rapiddisk/ At this point I havent tried it, maybe indeed kernel module compiling will be enough, maybe not.
What are some alternatives?
When comparing FEMU and rapiddisk you can also consider the following projects:
