 SSD will give you much bigger storage space (Vivid Unit has 32GB eMMC storage) and better read/write speed.  However the advantage of booting from SSD instead of eMMC is rather limited -- you will only see one or two seconds faster on boot.

 After the script finish running, you can reboot the device. Run command "lsblk" you will see the NVME SSD is mounted to '/', which means the root file system has been migrated to the SSD.

 By default the eMMC is no longer mounted. However the eMMC is still onboard and you can still use it as an extra 32GB storage. You just need to mount eMMC again. The command below is to mount eMMC to '/mnt':

			This eMMC still keeps its data. If you remove the NVME SSD, your Vivid Unit can still boot from its eMMC. However if you erase the data on eMMC, it will become un-bootable and you need to re-install OS to eMMC if you remove the SSD.
