SSD

How to use an external usb ssd as system storage.

Reasons

• A SSD is faster than a sd-card

• Has more read-write cycles

  • it will therefore not die as fast as a sd-card

• It is currently even cheaper

Needed

• SSD

• USB chassis

• SD card (needed temporarily if it is an older model)

• Raspberry Pi 2 or higher => 4 would be recommended

• Power supply with recommended amperage (since the usb device will suck relatively much power)

• Active cooling => per example a raspi chassis with a build-in 5V fan (since the power throughput will heat the board)

Notes

• You must not connect the external ssd via usb 3.x (blue one) since it might draw too much current and keep the device from booting at all

• If you have a raspberry pi 4 => try it without the sd card first; it might just work

HowTo

Raspberry Pi 4

• Download raspi imager

• Flash RaspberryPi OS on the usb-ssd (lite version is recommended but has no graphical user interface)

• Un- and re-plug both so they get automatically mounted on your computer

  • Add an empty ‘ssh’ file on each of the boot partitions as seen in this tutorial

  • If you are using windows make sure you enable it to show common file extensions

• Find the device in the network and connect to it via ssh per powershell (windows) or bash (linux) (default password is ‘raspberry’)

  $ ssh pi@IP-ADDRESS
  

Older models

• Download raspi imager

• Flash RaspberryPi OS on the sd card and usb-ssd (lite version is recommended but has no graphical user interface)

• Un- and re-plug both so they get automatically mounted on your computer

  • Add an empty ‘ssh’ file on each of the boot partitions as seen in this tutorial

  • If you are using windows make sure you enable it to show common file extensions

• Plug in the sd card and start the raspberry

• Find the device in the network and connect to it via ssh per powershell (windows) or bash (linux) (default password is ‘raspberry’)

  $ ssh pi@IP-ADDRESS
  

• Now we will set-up the usb device to be bootable as described in this raspi doc

  1. If you have an older board you might want to install all updates

  $ sudo apt-get update && apt-get full-upgrade --yes
  $ sudo reboot
  # wait to reboot and re-connect
  $ sudo raspi-config
  

  2. Select Advanced Options

  3. Bootloader version

  • choose latest and confirm choice

  4. Select Boot Order

  • Select USB

  5. Exit the menu via ‘finish’ (or Ctrl+D)

  $ sudo reboot
  

  6. The raspi will now boot to the usb-ssd

  7. Re-connect to the raspi and re-do the steps 2 to 5

  8. Disconnect the sd-card and you are done with this!
