for good overview it makes sense to label the harddisk partitions according to functionality (what is their purpose?)

GNU Linux bash – how to label partitions tune2fs (xfs & ext4)

# where is what & updates over changes (usb disk attached?) in realtime:

# define alias
alias loop_df='while true; do (clear; hostnamectl; echo '\''=========== looped harddisk info '\''; datum; dmesg|tail -n20; echo '\''=========== where is what'\''; harddisks; echo '\''=========== harddisk usage'\''; df -Th;) ; sleep 1 ; done'

# run it
loop_df

# looks like

lsblk -o "NAME,MAJ:MIN,RM,SIZE,RO,FSTYPE,MOUNTPOINT,UUID"
NAME                                          MAJ:MIN RM   SIZE RO FSTYPE      MOUNTPOINT UUID
