Yes, but the speed over usb is relatively poor.

If you've connected them permanently, yes. But you can't boot from an external hard drive or anything. But otherwise why not? You can theoretically buy a SD card to expand if your laptop has a slot that goes deep. Like HP, for example.

I've been doing this for 2 years.

You can boot from an external hard drive, that's wrong.

I do quite often because of my job.

What is booting?

I once heard that it can also be connected via hdmi. Is that correct? If so, does that have any advantages?

Or briefly not quite correctly explained, switching on the operating system.

No, that's nonsense. HDMI is mainly suitable for image transmission. USB is the best for OTG data transfer, but SATA is still better for hard drives. Especially in continuous operation.
