Nvme optimization settings (zram, ram log)

[Biasio95]

Hi, I just switched from an ancient ubuntu-rockchip install to armbian ubuntu 26.04 with the mainline kernel.

I did a bit of an unorthodox installation, I wanted to install on an nvme drive, and instead of using a microSD and then copying the system with armbian-install, since I didn't have a working microsd available I did a "manual" installation, I flashed rkspi_loader.img into the SPI taken from the armbian image and then flashed the armbian img directly to the nvme drive with an usb adapter from my PC.

 

All is good and working fine, but I'm wondering if I'm missing any settings that gets applied during the armbian-install process (are there any?) that are specific for nvme.

And regarding Zram, ram2log and other optimizations that armbian uses for SDs, how should I configure them?

 

My setup is a Radxa Rock 5B with 8GB of RAM with a Samsung 970 evo plus, should I disable zram and create a swapfile? Any other setting to look out for?

I think my hdparm -t speed is a bit low, around 1300 MB/s.

 

Thanks in advance
