SSD Upgrade For Raspberry Pi 3

I must been living in the trees. I didn’t know that the Raspberry Pi 3 can actually boot from USB and thought it was a new thing for Pi 4. Until I was reading about it then I realised that it’s already possible on the Pi 3. So, I quickly dug out my old SSD together with my Transcend enclosure and got to work.

My quick and dirty SSD upgrade for the Raspberry Pi 3

The process is very straightforward and the steps are documented on many websites.

Basically the steps are

Step 1: Clone the Micro SD into the SSD

dd if=/dev/mmcblk0 of=/dev/sda bs=1M

Step 2: Update /boot/firmware/config.txt and add this line


Step 3: Check the file system. This is an extra step which is optional but recommended. I did a fsck on the SSD before rebooting.

fsck -y /dev/sda2

Step 4: Remove SD card and reboot

The Raspberry Pi will boot from USB.

/dev/sda1 is a FAT32 partition so fsck is not required. (Or rather I’m lazy to do the chkdsk equivalent). Why I did the fsck is so that I can be sure the file system is ok and I can boot up the Raspberry Pi successfully. My monitor is stuck in office, so I want to do everything over ssh.

So, after the reboot, you get everything as per how it was with the micro SD, only faster and also a larger space. :)
