Not a dumb question, and no apology necessary! 

 

Loading the OS from an NVMe SSD (which is what your internal Optane drive is) is different from Ramroot:

• In normal mode, the boot loader will load the operating system (Euphony or AL, since both are based on Arch Linux) from the partition on the SSD that contains the root filesystem, i.e. that contains the / filesystem.
• In Ramroot mode, the boot loader proceeds with an extra step. Early in the boot process, it creates a RAM disk partition (/dev/zram0) in memory, copies the contents of the / partition from the SSD to this partition, and then completes the boot from this RAM disk partition. 

What this means is that the filesystem containing the kernel and the OS files is now completely in RAM.

 

Why exactly this sounds better is yet to be explained, although a lot of theories abound, having to do with reducing the latency of OS operations due to all OS files being in RAM.

 

It was also once stated that the prime reason for using Optane was that the latency was comparable with RAM (and the noise comparable with USB).

My trial code arrived in my spam mail. Took me a couple of days to find that out.
