This is very normal. Same performance on my DXP4800 Plus.

uGreen DXP4800 Pro would be my choice.

Thanks, Simon! I just wanted to make sure that I wasn't going crazy here and booting from some "ghost" USB drive I'd already removed

I bit the bullet and installed the 7.3 release candidate 2, and flashed it onto my (uGreen DXP4800+) 128gb boot drive. It's working fine, the license transferred, and it looks like everything is going ok. However, with the fact that we can now boot from an internal drive, I thought that would mean data configurations that used to get rebuilt on every USB drive boot would stay persistent on the /boot internal drive. Apparently, that's not the case. It appears that every time I reboot my machine, Unraid gets "built fresh" in memory once again. So, I'm assuming the "always runs in RAM" thing is still a thing, even though it's booting from an internal SSD. Do I have that right?

32 gb. I want to go to 64, but I'll have to sell one of my cars first

Holy hell! You must have some serious fan(s) in there to cool that monstrosity!
