I am having the exact same issue.
My original working setup was:
When I got a new RPi5-8G, I replaced the Pi4 with the Pi5 and its new RPi5 power supply. The Pi5 worked great when running from an SD card, except that disk IO was predictably quite slow. But trying to use the USB SSD that had been working on the Pi4 was a total fail. I got all the same problems as posters have mentioned above like system crashes, read-only file systems, rebooting problems, etc.
There is every indication that the Pi5 is having USB power problems. When the system craps out, the red LED on the wired mouse I have plugged into the USB2 port goes out and the mouse stops working. I do not understand why the old Pi4 with its 15W supply didn't have a problem if the SSD was a power hog, but all I can say is that the Pi4 setup worked perfectly. I also discovered that I could get further along in the Pi5 process if I unplugged the ethernet cable and used wifi instead. Ethernet does take significant power, so that kind of fit the power problem theory.
To further test the power hog theory, I bought a new Kingspec SATA SSD that takes 1/3 the power of the old Transcend SATA SSD. Sadly, the new lower-power SSD has all the same issues.
And finally, as per the this thread, I tried plugging the new Kingspec SSD into a USB 2.0 port on the Pi5. Presto: everything works perfectly. It's just that the USB2/SSD setup is barely faster than the SD card. So maybe there are a couple of issues going on, but it's weird that everything works perfectly with USB2 and not USB3.
My original working setup was:
- Raspberry Pi 4
- SSK USB3 enclosure (controller IC Chipset RTL9210B)
- Transcend 64G SATA SSD
