I’ve had the same experience with the SD cards. At least the most recent Raspberry Pis (e.g. the 4B) support firmware to boot from USB with just a little configuration effort. I just recently starting playing with this, booting a RPi 4B from a USB-attached Samsung T5 SSD. It seems to work mostly fine (caveat: see below). For other reasons, I’ve been running a RPi-specific version of Linux MATE, but Raspbian should work okay too. (I tried the RPi-specific image of Ubuntu, since I run Ubuntu on my Intel machines, but was not terribly impressed; slow interactive response.) One thing I did run into: if I try to plug too many USB devices in along with the SSD - e.g. in my case a mouse, keyboard, and GPS dongle - the system crashes because the SSD USB connection resets. It seems to be a power problem; I solved it with an external powered USB hub, leaving the SSD on a USB port on the RPi. :John -- J. L.
