Almost all of my SBCs run from USB storage, the performance improvements over SD card are obviously night and day; but I never had success with the direct boot from USB(official methods) and had to jump from SD card to USB storage after boot i.e. having only /boot on SD card. RPi 4 being newer, I assume it's designed with USB boot in mind and perhaps USB boot might work better than earlier iterations.
- gorgoiler 6y agoCan you elaborate on the performance improvements over SD card? (I have always assumed that the SD card had a much faster, more performant bus than USB. It sounds like that’s wrong?)
- Abishek_Muthian 6y agoSorry, that's not the case. Also I'm on USB SSD, which I should have mentioned. Even UHS card with over clocked card reader can reach only ~ 40 MB/s on RPi[1].
