... Either way, my point stands - I would always put disks on a hub
The Pi's 1.2A should be sufficient any portable drive, but that's assuming you have no other power hungry accessories, and of course, you have a proper 3A power supply (due to the higher power requirements of the SoC).
If you have multiple portable drives, or other power hungry accessories then you may find a hub is needed, but it's certainly not necessary, or even needed by many users. I've been using portable drives on my 3B and 3B+ computers for years without a hub.
The most important thing is to have a stable power supply. Many phone chargers have poor voltage regulation and will not maintain a stable 5V under load, and some cheap USB-C "charging" cables are only rate for 2.4A (or less). Long cables as well as extra connections or adapters can also contribute to voltage loss and low power troubles.
Note that a laptop drive in an enclosure is technically not a portable drive. Some laptop drives are shockingly power hungry, and putting one in an enclosure does not magically fix that. If you take a drive rated for 1A or more current and put it in an enclosure, don't be surprised when it doesn't work on a Raspberry Pi computer.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
