Which SD card for Raspberry Pi?

If you have a PI 3B or PI4, I would like to recommend the transfer to USB boot.

Say: Buy You have a fast USB stick (>= USB 3.0), play the operating system and work with it instead of using an SD card. You’ll see: your PI will be a bit faster. If you still want to invest in a USB3.x-SSD, get the optimum out of speed.

At PI4 you don’t have to do anything more than SD card out/USB-STick in/finished.

At PI 3, you have to set something before it can be used by USB boats:

1. On a (e.g.) Windows PC a USB stick/a USB SSD quite normal, like an SD card, also play with a RaspberryOS image.
2. Windows PC: Open memory card or work on running RPI
3. Open /boot/config.txt file with a text editor (on RPI with sudo work)
4. Insert the following line at the end:

5. program_usb_boot_mode=1

6. Use the SD card in the RPI and start the RPI (new)
7. Log in and check if the USB boot mode is active:

8. vcgencmd otp_dump | grep 17:

9. The result should be:

17:3020000a

• If so, shut down RPI and disconnect power supply.
• Remove memory card and insert USB stick.
• Plug in voltage and enjoy booting USB-Stick/SSD.
