yes All RPis have a big weak link: the connection to the disk drive, through USB and also the mSD cards where OS is located.

The USB cable, case, power adapter are very susceptible to fail, are the weakest link and will fail. Always. The mSD cards are terrible and always broke and give errors. The power adapter of a RPi you could never compare it with a stable power source of a PC. Are terrible.

And all these create several issues and you not even notice that your node is losing connection and give terrible link to thers.

RPis are NOT good for a sustained BTC/LN node. Are just toys. Yes are good for other destinations but not a BTC node
