I use a Pi3+ with a 5Tb powered HDD for media data (NTFS), a 120Gb M2
NGFF in USB enclosure for system (BTRFS) and 2Gb SD card for /boot.
I used rsync -avx to copy the system (except boot) to the SSD and then
changed cmdline.txt to refer to the UUID of the SSD partition.

New cmdline.txt (note there must be no line breaks) (note root=PARTUUID=):

dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1
root=PARTUUID=b23968df-fe3a-4a6d-aa38-4eac23db856e rootfstype=btrfs
elevator=deadline fsck.repair=yes rootwait quiet splash
plymouth.ignore-serial-consoles net.ifnames=0 biosdevname=0

New fstab:

# cat /etc/fstab

I took the setup instructions from here:
