I'm certainly no expert, but I've never been able to run a spinning disk HDD off of a raspberry pi without a powered USB hub. I imagine the thermals and form factor would be hurt pretty badly by including a plausible power supply.

It wouldn't need to be a spinning disk, I'm think SSD or NVME

  I still need to run an SSD off of a powered hub for an RPi to use it stably.

    Strange. What Pi? I’ve had a spinning 2.5” HDD connected to a Pi 3B+ for a few years now.

      maybe you're running a 4200rpm disk and the other person is running a 7200rpm disk. faster-spinning-plates would draw more power, I guess.

      RPI 4 -- the original revision. Whenever I ran it off the "official" power supply, I got disk errors. As soon as I moved over to a powered USB hub, I had no other issues. This was also with a keyboard and mouse plugged in, so maybe that had something to do with it. I was also trying to run it as a NAS, so it had a decent amount of IO. Maybe it could have been fixed with a better power supply, but switching over to the powered hub was easier to figure out.

Try a higher-quality power supply for your RPi.

  Honestly even with a high quality supply I'd tend to prefer if the drive were externally powered. I have flashbacks to the first generation Pis that would brownout and reboot if you plugged in a mouse or keyboard while it was running.

Running a spinny 2.5" 1TB drive on my pi zerow using a Samsung rapid charger to power the pi.

The Rasperry Pi 4 can power an 2.5 HDD just fine.
