well, it seems there are adapters out there that dont work well with USB3
UAS on Raspberry Pi4. what a pity! :( The link above has a fix. but the
fix will slow down the SSD. No UAS anymore.

I'm still checking if this was what caused the freezes, but i'm quite
sure it was.

This is the adapter (or the chip), in case you want to buy one for
yourself. Choose a different one for you Pi4 ;)

Someone in here has a tip wich msata usb3 adapter works well with a
Raspberry Pi4 and UAS enabled?
