I have 4 SSD drives connected to a single RPI4 currently, using a

USB hub.
Hmm... so maybe the USB connection is not directly relevant either and
the real issue is the power?
I'm forced to agree. The wall wart supplied with the pi kits is rather
under powered. I don't run them on less than a 5 volt 5 amp supply, and
like pocket, they only get rebooted when needsreboot says so after an
update. In 7 or so years of running a Sheldon lathe built in the 1940's,
first with an rpi3b which was pushed a bit and an rpi4b that doesn't
even breath hard, for at last 4, maybe 5 years, I've had one unscheduled
reboot. That I think is about 100x better uptime than I'm averaging
running the same linuxcnc software on wintel stuff. That 5 volt, 5 amp
supply is powering 5 other interfacing boards to get the job done. One
of its jobs is running a clone of the linuxcnc.org buildbot.
It Just Works...

That would be my best guess also
