Plasma freezes during high disk activity (solved) (discuss.tchncs.de)

I have a few dodgy cheap SSDs, so I'm not surprised by slow I/O performance in general. But my Plasma desktop frequently freezes for 1-3 seconds (including the cursor!) whenever there is high IO load, for example while installing a Steam game.

Updating the screen should be completely independent from I/O, shouldn't it? Is there anything I could've misconfigured in my Arch Linux? I'm running Plasma 6.1.4 in Wayland.

It might be interesting to determine whether the freezes are limited to Plasma or are happening within the kernel.

Have you tried Control+Alt+F1/F2/F3 ... F8, to see if switching virtual consoles still works while the freezes are happening?
Do you have another machine on the same network? You could use it to ssh into your desktop machine, and when the freezes are happening, see if they affect ssh interactivity.
