Not using NVMe is not a difference. It's not a different architecture. It's just simple circuit/space optimization, and has been done in other platforms as well. The controller, instead of being on the ssd module; it's present onboard the device.
I bought a NanoPi R6C in the past in the hope that it's going to be a nice mini pc to run all my containers with super low power usage or router. But the software was bad, really bad. I found https://github.com/Joshua-Riek/ubuntu-rockchip/ , it was godsend but still had some shortcomings. after 2 years, it's bit stable but I just keep it around as a backup route to access my homelab incase the main machines go down.
I just loved road rash, I had the demo version initially, I used to call it demo rash. Once in a race I accidentally jumped on a building, it was first open world experience for me!
I remember back in 2006 I used to browse overclock forums to overclock my pentium 4, I tons of fun consuming lots of instructions, I learned the bios, changed PLL clocks, mem clocks etc.
The major issue is these days most software is electron based or a webapp. I miss the days of 98/XP, where you'd find tons of desktop software. A PC actually felt something that had a purpose. Even if you spin up a XP/98(especially 98/2000 VM) now, you'd see the entire OS feels something that you can spend some time on. Nowadays most PCs feel like a random terminal where I open the browser and do some basic work(except for gaming ofcourse).
I really hate the UX of win 11 , even 10 isn't much better compared to XP.
I really hope we go back to that old era.
