Recently, the Raspberry Pi Foundation announced a USB boot beta for the Raspberry Pi 4. For a very long time, the top complaint I've had with the Raspberry Pi is limited I/O speed (especially for the main boot volume). And on older Pis, with the maximum external disk speed limited especially by the USB 2.0 bus—which was shared with the network adapter, limiting its bandwidth further—even USB booting didn't make things amazing.
But the Pi 4 not only separated the network adapter from the USB bus, it also has USB 3.0, which can be 10x faster than USB 2.0 (theoretically). So when the USB boot beta was announced, I wanted to put it through its paces. And after testing it a bit, I decided to use the Pi 4 as my full-time workstation for a day, to see whether it can cope and where it falls short. I'll be posting a video and blog post with more detail on that experience very soon.
Update: I now have a video that goes along with this blog post:
